Signal Description

TIO0

Input or

Output

GPIO Input Timer 0 Schmitt-Trigger Input/Output—When timer 0 functions as an

external event counter or in measurement mode, TIO0 is used as input.

When timer 0 functions in watchdog, timer, or pulse modulation mode,

TIO0 is used as output.

The default mode after reset is GPIO input. This can be changed to

output or configured as a timer input/output through the timer 0

control/status register (TCSR0). If TIO0 is not being used, it is

recommended to either define it as GPIO output immediately at the

beginning of operation or leave it defined as GPIO input.

Internal Pull down resistor.

This input is 5 V tolerant

TIO1

Input or

Output

Watchdog

Timer

Output

Timer 1 Schmitt-Trigger Input/Output—When timer 1 functions as an

external event counter or in measurement mode, TIO1 is used as input.

When timer 1 functions in watchdog, timer, or pulse modulation mode,

TIO1 is used as output.

The default mode after reset is GPIO input. This can be changed to

output or configured as a timer input/output through the timer

1control/status register (TCSR1). If TIO1 is not being used, it is

recommended to either define it as GPIO output immediately at the

beginning of operation or leave it defined as GPIO input.

WDT

Output

WDT—When this pin is configured as a hardware watchdog timer pin,

this signal is asserted low when the hardware watchdog timer counts

down to zero.

Internal Pull down resistor.

This input is 5 V tolerant

TIO2

Input or

Output

PLOCK

Output

Timer 2 Schmitt-Trigger Input/Output—When timer 2 functions as an

external event counter or in measurement mode, TIO2 is used as input.

When timer 2 functions in watchdog, timer, or pulse modulation mode,

TIO2 is used as output.

The default mode after reset is GPIO input. This can be changed to

output or configured as a timer input/output through the timer

control/status register (TCSR2). If TIO2 is not being used, it is

recommended to either define it as GPIO output immediately at the

beginning of operation or leave it defined as GPIO input .
