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.
