Hi,
According to MSP432 TRM, any unused port pins should be configured as output pin or input pin with internal pullup or pulldown resistor enabled to reduce power consumption.
Does the same apply when running MSP432 with TI RTOS with deep sleep power policy?
Since the enableParking is true by default in PowerMSP432_config, is it true that user have to initialize every unused GPIO pins in BoardGpioInitTable[] so that PIN state is defined during LPM?
I have a customized board, and I am seeing 7-8 uA extra current when the MCU is in LPM. Does anyone know on average how much current is wasted for each unused pin if it is not configured? I tried to set some of the unused pins as output pin with output low, but I didn't see obvious current drop.
Any suggestions? Thanks for your time.
