Timers
Overview
Architecture
PS017610-0404
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:
•
•
•
•
•
•
•
In addition to the timers described in this chapter, the Baud Rate Generators for any
unused UART, SPI, or I
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.
Figure 66 illustrates the architecture of the timers.
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
