Item 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
