9.4 Timer
V
9.4.1 Overview
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 (
φ
/128,
φ
/64,
φ
/32,
φ
/16,
φ
/8,
φ
/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.
