Is it possible to use the RST switch for another action on the Xiao Sense nRF52840? I wanted to use it as an ON/OFF switch, where OFF would be deep sleep:

// Put device into deep sleep mode
  NRF_POWER->SYSTEMOFF = 1;

Based on the schematic, and an excerpt of the schematic below, it doesn’t seem possible. But I wanted to double check. Thanks

maybe the boot button could be programmed… but probably not the reset… lets see what PJGlasso has to say about it!
