Description
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.
PIO0_0 — General purpose digital input/output pin. Also serves
as wake-up pin from Deep-sleep mode.
RTS0 — Request To Send output for UART0.
PIO0_1 — General purpose digital input/output pin. Also serves
as wake-up pin from Deep-sleep mode.
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. Also serves
as wake-up pin from Deep-sleep mode.
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. Also serves
as wake-up pin from Deep-sleep mode.
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.
PIO0_4 — General purpose digital input/output pin. Also serves
as wake-up pin from Deep-sleep mode.
DSR0 — Data Set Ready input for UART0.
CT32B0_CAP3 — Capture input, channel 3 for 32-bit timer 0.
CT32B0_MAT3 — Match output, channel 3 for 32-bit timer 0.
PIO0_5 — General purpose digital input/output pin. Also serves
as wake-up pin from Deep-sleep mode.
DCD0 — Data Carrier Detect input for UART0.
