Specification

Timers

Six on-chip timers

• Timer A: 8-bit timer

Count-up timer with selection of eight internal clock signals divided from the

system clock (

φ)* and four clock signals divided from the watch clock (φ

w)*

• Asynchronous event counter: 16-bit timer

 Count-up timer able to count asynchronous external events

independently of the MCU's internal clocks

Asynchronous external events can be counted (both rising and falling edge

detection possible)

• Timer C: 8-bit timer

 Count-up/down timer with selection of seven internal clock signals or

event input from external pin

 Auto-reloading

• Timer F: 16-bit timer

 Can be used as two independent 8-bit timers

 Count-up timer with selection of four internal clock signals or event input

from external pin

 Provision for toggle output by means of compare-match function

• Timer G: 8-bit timer

 Count-up timer with selection of four internal clock signals

 Incorporates input capture function (built-in noise canceler)

• Watchdog timer

 Reset signal generated by overflow of 8-bit counter
