Timer F is a 16-bit timer with a built-in output compare function. As well as counting external
events, timer F also provides for counter resetting, interrupt request generation, toggle output, etc.,
using compare match signals. Timer F can also be used as two independent 8-bit timers (timer FH
and timer FL).
Features
Features of timer F are given below.
• Choice of four internal clock sources (φ/32, φ/16, φ/4, φw/4) or an external clock (can be used
• TMOFH/TMOFL pin toggle output provided using a single compare match signal (toggle
• Counter resetting by a compare match signal
• Two interrupt sources: one compare match, one overflow
• Can operate as two independent 8-bit timers (timer FH and timer FL) (in 8-bit mode).

Note: * When timer F operates as a 16-bit timer, it operates on the timer FL overflow signal.
• Operation in watch mode, subactive mode, and subsleep mode
• Use of module standby mode enables this module to be placed in standby mode independently
as an external event counter)

When φw/4 is selected as the internal clock, timer F can operate in watch mode, subactive
mode, and subsleep mode.
