Description

RESET/PIO0_0

C1[2]

B2[2]

yes

I; PU

RESET — External reset input with 20 ns glitch

filter. A LOW -going pulse as short as 50 ns on this

pin resets the device, causing I/O ports and

peripherals to take on their default states, and

processor execution to begin at address 0.

I/O

PIO0_0 — General purpose digital input/output pin.

PIO0_1/CLKOUT/

CT32B0_MAT2

-C1[3]

yes

I/O

I; PU

PIO0_1 — General purpose digital input/output pin.

A LOW level on this pin during reset starts the ISP

command handler.

O-

CLKOUT — Clockout pin.

O-

CT32B0_MAT2 — Match output 2 for 32-bit timer 0.

PIO0_6/SCK0

A1[3]

yes

I/O

I;PU

PIO0_6 — General purpose digital input/output pin.

I/O

SCK0 — Serial clock for SPI0.

PIO0_8/MISO/

CT16B0_MAT0

A2[3]

A3[3]

yes

I/O

I; PU

PIO0_8 — General purpose digital input/output pin.

I/O

MISO0 — Master In Slave Out for SPI.

O-

CT16B0_MAT0 — Match output 0 for 16-bit timer 0.

PIO0_9/MOSI/

CT16B0_MAT1

A3[3]

A4[3]

yes

I/O

I; PU

PIO0_9 — General purpose digital input/output pin.

I/O

MOSI0 — Master Out Slave In for SPI.

O-

CT16B0_MAT1 — Match output 1 for 16-bit timer 0.

SWCLK/

PIO0_10/

SCK0/CT16B0_MAT2

A4[3]

A2[3]

yes

I; PU

SWCLK — Serial wire clock.

I/O

PIO0_10 — General purpose digital input/output

pin.

I/O

SCK0 — Serial clock for SPI0.

O-

CT16B0_MAT2 — Match output 2 for 16-bit timer 0.

R/PIO0_11/

AD0/CT32B0_MAT3

B4[4]

yes

I; PU

R — Reserved.

I/O

PIO0_11 — General purpose digital input/output

pin.

I-

AD0 — A/D converter, input 0.

I-

CT32B0_MAT3 — Match output 3 for 32-bit timer 0.

R/PIO1_0/

AD1/CT32B1_CAP0

B3[4]

yes

I; PU

R — Reserved.

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

R/PIO1_1/

AD2/CT32B1_MAT0
