Bug Fixes
Fixed bug in LPI2C_MasterInit that the MCFGR2’s value set in LPI2C_MasterSetBaudRate may be overwritten by mistake.
[2.3.2]
Improvements
Initialized the EDMA configuration structure in the LPI2C EDMA driver.
[2.3.1]
Improvements
Updated LPI2C_GetCyclesForWidth to add the parameter of minimum cycle, because for master SDA/SCL filter, master bus idle/pin low timeout and slave SDA/SCL filter configuration, 0 means disabling the feature and cannot be used.
Bug Fixes
Fixed bug in LPI2C_SlaveTransferHandleIRQ that when restart detect event happens the transfer structure should not be cleared.
Fixed bug in LPI2C_RunTransferStateMachine, that when only slave address is transferred or there is still data remaining in tx FIFO the last byte’s nack cannot be ignored.
Fixed bug in slave filter doze enable, that when FILTDZ is set it means disable rather than enable.
Fixed bug in the usage of LPI2C_GetCyclesForWidth. First its return value cannot be used directly to configure the slave FILTSDA, FILTSCL, DATAVD or CLKHOLD, because the real cycle width for them should be FILTSDA+3, FILTSCL+3, FILTSCL+DATAVD+3 and CLKHOLD+3. Second when cycle period is not affected by the prescaler value, prescaler value should be passed as 0 rather than 1.
Fixed wrong default setting for LPI2C slave. If enabling the slave tx SCL stall, then the default clock hold time should be set to 250ns according to I2C spec for 100kHz standard mode baudrate.
Fixed bug that before pushing command to the tx FIFO the FIFO occupation should be checked first in case FIFO overflow.
[2.3.0]
New Features
Supported reading more than 256 bytes of data in one transfer as master.
Added API LPI2C_GetInstance.
Bug Fixes
Fixed bug in LPI2C_MasterTransferAbortEDMA, LPI2C_MasterTransferAbort and LPI2C_MasterTransferHandleIRQ that before sending stop signal whether master is active and whether stop signal has been sent should be checked, to make sure no FIFO error or bus error will be caused.
Fixed bug in LPI2C master EDMA transactional layer that the bus error cannot be caught and returned by user callback, by monitoring bus error events in interrupt handler.
Fixed bug in LPI2C_GetCyclesForWidth that the parameter used to calculate clock cycle should be 2^prescaler rather than prescaler.
Fixed bug in LPI2C_MasterInit that timeout value should be configured after baudrate, since the timeout calculation needs prescaler as parameter which is changed during baudrate configuration.
Fixed bug in LPI2C_MasterTransferHandleIRQ and LPI2C_RunTransferStateMachine that when master writes with no stop signal, need to first make sure no data remains in the tx FIFO before finishes the transfer.
[2.2.0]
Bug Fixes
Fixed issue that the SCL high time, start hold time and stop setup time do not meet I2C specification, by changing the configuration of data valid delay, setup hold delay, clock high and low parameters.
MISRA C-2012 issue fixed.
Fixed rule 8.4, 13.5, 17.7, 20.8.
[2.1.12]
Bug Fixes
Fixed MISRA advisory 15.5 issues.
[2.1.11]
Bug Fixes
Fixed the bug that, during master non-blocking transfer, after the last byte is sent/received, the kLPI2C_MasterNackDetectFlag is expected, so master should not check and clear kLPI2C_MasterNackDetectFlag when remainingBytes is zero, in case FIFO is emptied when stop command has not been sent yet.
Fixed the bug that, during non-blocking transfer slave may nack master while master is busy filling tx FIFO, and NDF may not be handled properly.
[2.1.10]
Bug Fixes
MISRA C-2012 issue fixed.
Fixed rule 10.3, 14.4, 15.5.
Fixed unaligned access issue in LPI2C_RunTransferStateMachine.
Fixed uninitialized variable issue in LPI2C_MasterTransferHandleIRQ.
Used linked TCD to disable tx and enable rx in read operation to fix the issue that for platform sharing the same DMA request with tx and rx, during LPI2C read operation if interrupt with higher priority happened exactly after command was sent and before tx disabled, potentially both tx and rx could trigger dma and cause trouble.
Fixed MISRA issues.
Fixed rules 10.1, 10.3, 10.4, 11.6, 11.9, 14.4, 17.7.
Fixed the waitTimes variable not re-assignment issue for each byte read.

Fixed Coverity issue of unchecked return value in I2C_RTOS_Transfer.
Fixed Coverity issue of operands did not affect the result in LPI2C_SlaveReceive and LPI2C_SlaveSend.
Removed STOP signal wait when NAK detected.
Cleared slave repeat start flag before transmission started in LPI2C_SlaveSend/LPI2C_SlaveReceive. The issue was that LPI2C_SlaveSend/LPI2C_SlaveReceive did not handle with the reserved repeat start flag. This caused the next slave to send a break, and the master was always in the receive data status, but could not receive data.
[2.1.8]
Bug Fixes
Fixed the transfer issue with LPI2C_MasterTransferNonBlocking, kLPI2C_TransferNoStopFlag, with the wait transfer done through callback in a way of not doing a blocking transfer.
Fixed the issue that STOP signal did not appear in the bus when NAK event occurred.
[2.1.7]
Bug Fixes
Cleared the stopflag before transmission started in LPI2C_SlaveSend/LPI2C_SlaveReceive. The issue was that LPI2C_SlaveSend/LPI2C_SlaveReceive did not handle with the reserved stop flag and caused the next slave to send a break, and the master always stayed in the receive data status but could not receive data.
[2.1.6]
Bug Fixes
Fixed driver MISRA build error and C++ build error in LPI2C_MasterSend and LPI2C_SlaveSend.
Reset FIFO in LPI2C Master Transfer functions to avoid any byte still remaining in FIFO during last transfer.
Fixed the issue that LPI2C_MasterStop did not return the correct NAK status in the bus for second transfer to the non-existing slave address.
[2.1.5]
Bug Fixes
Extended the Driver IRQ handler to support LPI2C4.
Changed to use ARRAY_SIZE(kLpi2cBases) instead of FEATURE COUNT to decide the array size for handle pointer array.
[2.1.4]
Bug Fixes
Fixed the LPI2C_MasterTransferEDMA receive issue when LPI2C shared same request source with TX/RX DMA request. Previously, the API used scatter-gather method, which handled the command transfer first, then the linked TCD which was pre-set with the receive data transfer. The issue was that the TX DMA request and the RX DMA request were both enabled, so when the DMA finished the first command TCD transfer and handled the receive data TCD, the TX DMA request still happened due to empty TX FIFO. The result was that the RX DMA transfer would start without waiting on the expected RX DMA request.
Fixed the issue by enabling IntMajor interrupt for the command TCD and checking if there was a linked TCD to disable the TX DMA request in LPI2C_MasterEDMACallback API.
[2.1.3]
Improvements
Added LPI2C_WATI_TIMEOUT macro to allow the user to specify the timeout times for waiting flags in functional API and blocking transfer API.
Added LPI2C_MasterTransferBlocking API.
[2.1.2]
Bug Fixes
In LPI2C_SlaveTransferHandleIRQ, reset the slave status to idle when stop flag was detected.
[2.1.1]
Bug Fixes
Disabled the auto-stop feature in eDMA driver. Previously, the auto-stop feature was enabled at transfer when transferring with stop flag. Since transfer was without stop flag and the auto-stop feature was enabled, when starting a new transfer with stop flag, the stop flag would be sent before the new transfer started, causing unsuccesful sending of the start flag, so the transfer could not start.
Changed default slave configuration with address stall false.
[2.1.0]
Improvements
API name changed:
LPI2C_MasterTransferCreateHandle -> LPI2C_MasterCreateHandle.
LPI2C_MasterTransferGetCount -> LPI2C_MasterGetTransferCount.

[2.2.4]
Improvements
Added hardware flow control function support.
Added idle-line-detecting feature in LPUART_TransferNonBlocking function. If an idle line is detected, a callback is triggered with status kStatus_LPUART_IdleLineDetected returned. This feature may be useful when the received Bytes is less than the expected received data size. Before triggering the callback, data in the FIFO (if has FIFO) is read out, and no interrupt will be disabled, except for that the receive data size reaches 0.
Enabled the RX FIFO watermark function. With the idle-line-detecting feature enabled, users can set the watermark value to whatever you want (should be less than the RX FIFO size). Data is received and a callback will be triggered when data receive ends.
[2.2.3]
Improvements
Changed parameter type in LPUART_RTOS_Init struct from rtos_lpuart_config to lpuart_rtos_config_t.
Bug Fixes
Disabled LPUART receive interrupt instead of all NVICs when reading data from ring buffer. Otherwise when the ring buffer is used, receive nonblocking method will disable all NVICs to protect the ring buffer. This may has a negative effect on other IPs that are using the interrupt.
