Timers
The Z8 Encore! XP F64xx Series products contain up to four 16-bit reloadable timers that
can be used for timing, event counting or generation of pulse-width modulated 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 can also be used to provide basic timing functionality. For
information about using the baud rate generators as timers, see the respective serial com-
munication peripheral. Timer 3 is unavailable in the 44-pin package devices.
