This LSI has an on-chip 8-bit timer module (TMR_0 and TMR_1) with two channels operating on
the basis of an 8-bit counter. The 8-bit timer module can be used as a multifunction timer in a
variety of applications, such as generation of counter reset, interrupt requests, and pulse output
with an arbitrary duty cycle using a compare-match signal with two registers.
This LSI also has a similar on-chip 8-bit timer module (TMR_Y and TMR_X) with two channels.
12.1
• Selection of clock sources
• Selection of three ways to clear the counters
• Timer output controlled by two compare-match signals
• Cascading of TMR_0 and TMR_1
• Multiple interrupt sources for each channel
Figures 12.1 and 12.2 show block diagrams of 8-bit timers.
An input capture function is added to TMR_X.
