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.
LPC122x pin description
To enable a peripheral function, 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.
