Overview

The MCUXpresso SDK provides APIs for MCUXpresso SDK devices' src operation.

The System Reset Controller(SRC) is responsible for generation of all reset signals and the boot argument latching. To get the latched boot arguments, the driver provides "Latched Boot Arguments Related Interfaces" function group, all APIs in this group can be used to get the latched boot arguments. There are four situations cause an certain reset event:

Power-on Reset
Global System reset request
Software configuration
Low-power mode transaction The System Reset Controller(SRC) can generate reset events of the last 3 types. For the "Global System reset request", the APIs in "Global System Related Interfaces" can be used to set global reset mode or get the global reset status flags. For the "Software configuration", the APIs in "Slice Software Reset Related Interfaces" can be used. For the "Low-power mode transaction", the APIs in "Slice Low-Power Mode Transition Related Interfaces" can be used. If the reset behavior is controlled by CPU low-power mode, the function SRC_SetSliceDomainModeAuthentication() and SRC_SetSliceDomainModeConfig() can be invoked. If the the reset behavior is controlled by set point the function SRC_SetSliceSetPointAuthentication() and SRC_SetSliceSetPointConfig() can be used.
