R/PIO0_11/
AD0/CT32B0_MAT3
32
[5][2]
I R — Reserved. Configure for an alternate function in the IOCONFIG block.
I/O PIO0_11 — General purpose digital input/output pin.
I AD0 — A/D converter, input 0.
O CT32B0_MAT3 — Match output 3 for 32-bit timer 0.
PIO1_0 to PIO1_11 I/O Port 1 — Port 1 is a 12-bit I/O port with individual direction and function
controls for each bit. The operation of port 1 pins depends on the function
selected through the IOCONFIG register block.
R/PIO1_0/
AD1/CT32B1_CAP0
33
[5][2]
I R — Reserved. Configure for an alternate function in the IOCONFIG block.
I/O PIO1_0 — General purpose digital input/output pin.
I AD1 — A/D converter, input 1.
I CT32B1_CAP0 — Capture input 0 for 32-bit timer 1.
R/PIO1_1/
AD2/CT32B1_MAT0

O R — Reserved. Configure for an alternate function in the IOCONFIG block.
I/O PIO1_1 — General purpose digital input/output pin.
I AD2 — A/D converter, input 2.
O CT32B1_MAT0 — Match output 0 for 32-bit timer 1.
R/PIO1_2/
AD3/CT32B1_MAT1
35
[5]
I R — Reserved. Configure for an alternate function in the IOCONFIG block.
I/O PIO1_2 — General purpose digital input/output pin.
I AD3 — A/D converter, input 3.
O CT32B1_MAT1 — Match output 1 for 32-bit timer 1.
SWDIO/PIO1_3/AD4/
CT32B1_MAT2
39
[5]
I/O SWDIO — Serial wire debug input/output.
I/O PIO1_3 — General purpose digital input/output pin.
I AD4 — A/D converter, input 4.
O CT32B1_MAT2 — Match output 2 for 32-bit timer 1.
PIO1_4/AD5/
CT32B1_MAT3/WAKEUP
40
[5]
I/O PIO1_4 — General purpose digital input/output pin. In Deep power-down
mode, this pin serves as the Deep power-down mode wake-up pin with 20
ns glitch filter. Pull this pin HIGH externally before entering Deep
power-down mode. Pull this pin LOW to exit Deep power-down mode. A
LOW-going pulse as short as 50 ns wakes up the part.
I AD5 — A/D converter, input 5.
O CT32B1_MAT3 — Match output 3 for 32-bit timer 1.
PIO1_5/RTS
/
CT32B0_CAP0
45
[3]
I/O PIO1_5 — General purpose digital input/output pin.
O RTS
— Request To Send output for UART.
I CT32B0_CAP0 — Capture input 0 for 32-bit timer 0.
PIO1_6/RXD/
CT32B0_MAT0
46
[3]
I/O PIO1_6 — General purpose digital input/output pin.
I RXD — Receiver input for UART.
O CT32B0_MAT0 — Match output 0 for 32-bit timer 0.
PIO1_7/TXD/
CT32B0_MAT1
47
[3]
I/O PIO1_7 — General purpose digital input/output pin.
O TXD — Transmitter output for UART.
O CT32B0_MAT1 — Match output 1 for 32-bit timer 0.
PIO1_8/CT16B1_CAP0 9
[3]
I/O PIO1_8 — General purpose digital input/output pin.
I CT16B1_CAP0 — Capture input 0 for 16-bit timer 1.
