Timers
Overview
The Z8F640x family products contain three to four 16-bit reloadable timers that can be
used for timing, event counting, or generation of pulse-width modulated (PWM) signals.
The timers’ features include:
•
•
•
•
•
16-bit reload counter
Programmable prescaler with prescale values from 1 to 128
PWM output generation
Capture and compare capability
External input pin for timer input, clock gating, or capture signal. External input pin
signal frequency is limited to a maximum of one-fourth the system clock frequency.
•
•
Timer output pin
Timer interrupt
In addition to the timers described in this chapter, the Baud Rate Generators for any
unused UART, SPI, or I2C peripherals may also be used to provide basic timing function-
ality. Refer to the respective serial communication peripheral chapters for information on
using the Baud Rate Generators as timers. Timer 3 is unavailable in the 40- and 44-pin
packages.
