Confusing about the system off mode of 52832

[Gz]

Hi,

I was testing the pwr_mgmt project in the nRF5_SDK_13.0.0 with my 52DK, the system off mode seems work fine ,cause the log information is right,but the question is that when 52832 enters system off mode the four leds are still light, shouldn't them off?

Hi,

All GPIO configuration is retained is System Off, so if the LED is on when entering System Off mode, it will also stay on in System Off mode.

From the GPIO chapter in the Product Specification:

The PIN_CNF registers are retained registers. See POWER — Power supply chapter for more information about retained registers.
