Product Specification

Timers

Overview

These Z8 Encore! XP® 4K Series products contain two 16-bit reloadable timers that can

be used for timing, event counting, or generation of pulse-width modulated (PWM) sig-

nals. 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 Generator of the UART

(if unused) may also provide basic timing functionality. Refer to chapter UART on

page 89 for information about using the Baud Rate Generator as an additional timer.

Architecture

Figure 9 illustrates the architecture of the timers.
