6.2 Pin description
All pins except the supply pins can have more than one function as shown in
pin function is selected through the pin’s IOCON register in the IOCONFIG block. The
multiplexed functions (see
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.

RTS0 — Request To Send output for UART0.
PIO0_1 — General purpose digital input/output pin.
RXD0 — Receiver input for UART0.
CT32B0_CAP0 — Capture input, channel 0 for 32-bit timer 0.
CT32B0_MAT0 — Match output, channel 0 for 32-bit timer 0.
PIO0_2 — General purpose digital input/output pin.
TXD0 — Transmitter output for UART0.
CT32B0_CAP1 — Capture input, channel 1 for 32-bit timer 0.
CT32B0_MAT1 — Match output, channel 1 for 32-bit timer 0.
PIO0_3 — General purpose digital input/output pin.
DTR0 — Data Terminal Ready output for UART0.
CT32B0_CAP2 — Capture input, channel 2 for 32-bit timer 0.
CT32B0_MAT2 — Match output, channel 2 for 32-bit timer 0.
