anonymous enum

Enumerator
kStatus_LPI2C_Busy	The master is already performing a transfer.
kStatus_LPI2C_Idle	The slave driver is idle.
kStatus_LPI2C_Nak	The slave device sent a NAK in response to a byte.
kStatus_LPI2C_FifoError	FIFO under run or overrun.
kStatus_LPI2C_BitError	Transferred bit was not seen on the bus.
kStatus_LPI2C_ArbitrationLost	Arbitration lost error.
kStatus_LPI2C_PinLowTimeout	SCL or SDA were held low longer than the timeout.
kStatus_LPI2C_NoTransferInProgress	Attempt to abort a transfer when one is not in progress.
kStatus_LPI2C_DmaRequestFail	DMA request failed.
kStatus_LPI2C_Timeout	Timeout polling status flags.
