* SYS_LED and COL_x are open-drain, output logic is inverted.
*
* Unless requested by the user through REG_ID_PWR_CTRL register or by removing
* the batteries, pressing the power button when running now put the STM32 in
* low-power stop mode and shutdown the PICO board.
* It's the only mean to keep the RTC functional.
* A full shutdown using AXP2101 power-off or by removing the batteries will
* reset the RTC and disable auto wake-up feature.
