SS
Pin state at reset for default function: I = Input; O = Output; PU = internal pull-up enabled; IA = inactive, no pull-up/down enabled.
3.3 V tolerant, digital I/O pin; default: pull-up enabled, no hysteresis.
I
3.3 V tolerant, digital I/O pin with RESET function; default: pull-up enabled, no hysteresis. An external pull-up resistor is required on this
pin for the Deep power-down mode.
3.3 V tolerant, digital I/O pin with analog function; default: pull-up enabled, no hysteresis.
3.3 V tolerant, digital I/O pin with analog function and WAKEUP function; default: pull-up enabled, no hysteresis.
3.3 V tolerant, high-drive digital I/O pin; default: pull-up enabled, no hysteresis.
2
C-bus pins; 5 V tolerant; open-drain; default: no pull-up/pull-down; no hysteresis.
To enable a peripheral function on a pin, find the corresponding port pin, or select a port
pin if the function is multiplexed, and program the port pin’s IOCONFIG register to enable
that function. The primary SWD functions and RESET are the default functions on their
pins after reset, all other digital pins default to GPIO.
