Will GPIO maintain its original state at wake-up reset as GPIO remains its original state after entering SPD mode? 日付:2018-11-26
GPIO can maintain its original state after entering Standby Power-down mode (SPD0/1 mode). However, after wake-up reset, the GPIO status may be reset due to different trigger sources. The GPIO status includes MFP, I/O modes, and High/Low.

In summary, the GPIO state can be maintained when the trigger source is the wake-up source, and the GPIO state will be reset when the trigger source is the reset source.
In addition, if the GPIO status is reset when the trigger source is the wake-up source, user can set the IOHR (CLK_IOPDCTL[0]) register to reset the GPIO status.
