Hello,
I have a question regarding the sys_poweroff()
function. In my device, there is a mode where the board (including the nRF52840 chip and GPIOs) remains powered, but the chip itself is turned off using sys_poweroff()
.
I came across a thread on the Nordic DevZone discussing the default state of the nRF52840's GPIOs (NRF52840 GPIO default state - Nordic Q&A - Nordic DevZone - Nordic DevZone). It mentions that GPIOs should not be powered if the chip is unpowered. My concern is whether this requirement applies to the state induced by sys_poweroff()
, or if it only pertains to situations where the chip is physically disconnected from its power supply.
Could you please help clarify this?
Thanks in advance!
