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