9.4.1
Timer V is an 8-bit timer based on an 8-bit counter. Timer V counts external events. Also compare
match signals can be used to reset the counter, request an interrupt, or output a pulse signal with an
arbitrary duty cycle. Counting can be initiated by a trigger input at the TRGV pin, enabling pulse
output control to be synchronized to the trigger, with an arbitrary delay from the trigger input.
Features
Features of timer V are given below.
Choice of six internal clock sources ( /128, /64, /32, /16, /8, /4) or an external clock (can
be used as an external event counter).
Counter can be cleared by compare match A or B, or by an external reset signal. If the count
stop function is selected, the counter can be halted when cleared.
Timer output is controlled by two independent compare match signals, enabling pulse output
with an arbitrary duty cycle, PWM output, and other applications.
Three interrupt sources: two compare match, one overflow
Counting can be initiated by trigger input at the TRGV pin. The rising edge, falling edge, or
both edges of the TRGV input can be selected.
