LPC122x
32-bit ARM Cortex-M0 microcontroller
6.2 Pin description
All pins except the supply pins can have more than one function as shown in Table 3. The
pin function is selected through the pin’s IOCON register in the IOCONFIG block. The
multiplexed functions (see Table 4) include the counter/timer inputs and outputs, the
UART receive, transmit, and control functions, and the serial wire debug functions.
For each pin, the default function is listed first together with the pin’s reset state.
Table 3.

PIO0_0 to PIO0_31
I/O
Port 0 — Port 0 is a 32-bit I/O port with individual direction and
function controls for each bit. The operation of port 0 pins
depends on the function selected through the IOCONFIG
register block.
