[1] The GPIO port is a 12-bit I/O port with individual direction and function controls for each bit. The operation of port 0 pads
depends on the function selected through the IOCONFIG register block.
[2] If external wake-up is enabled on this pad, it must be pulled HIGH before entering Deep power-down mode and pulled
LOW for a minimum of 100 μs to exit Deep power-down mode.
[3] Open drain, no pull-up or pull down.
[4] The analog port is a 6-input analog I/O port with enable control for each pad.
[5] A LOW on this pin resets the device. This reset causes I/O ports and peripherals to take on their default states, and
processor execution to begin at address 0. It has weak pull-up to V
BAT
or internal NFC voltage (whichever is highest).
