Timer F

9.3.1

Overview

Timer F is a 16-bit timer with an output compare function. Compare match signals can be used to

reset the counter, request an interrupt, or toggle the output. Timer F can also be used for external

event counting, and can operate 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 (ø/32, ø/16, ø/4, ø/2) or an external clock (can be used as

an external event counter).

• Output from pin TMOFH is toggled by one compare match signal (the initial value of the

toggle output can be set).

• Counter can be reset by the compare match signal.

• Two interrupt sources: counter overflow and compare match.

• Can operate as two independent 8-bit timers (timer FH and timer FL) in 8-bit mode.

Timer FH

 8-bit timer (clocked by timer FL overflow signals when timer F operates as a 16-bit timer).

 Choice of four internal clocks (ø/32, ø/16, ø/4, ø/2).

 Output from pin TMOFH is toggled by one compare match signal (the initial value of the

toggle output can be set).

 Counter can be reset by the compare match signal.

 Two interrupt sources: counter overflow and compare match.

Timer FL

 8-bit timer/event counter

 Choice of four internal clocks (ø/32, ø/16, ø/4, ø/2) or event input at pin TMIF.

 Output from pin TMOFL is toggled by one compare match signal (the initial value of the

toggle output can be set).

 Counter can be reset by the compare match signal.

 Two interrupt sources: counter overflow and compare match.
