TIMH265A_000020020800
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.
10.1
Selection of clock sources
Selection of three ways to clear the counters
Timer output controlled by two compare-match signals
Cascading of two channels
TMR_0, TMR_1: The counter input clock can be selected from six internal clocks and an
external clock
TMR_Y, TMR_X: The counter input clock can be selected from six internal clocks *
an external clock
The counters can be cleared on compare-match A or compare-match B, or by an external
reset signal.
The timer output signal in each channel is controlled by two independent compare-match
signals, enabling the timer to be used for various applications, such as the generation of
pulse output or PWM output with an arbitrary duty cycle.
Cascading of TMR_0 and TMR_1
Operation as a 16-bit timer can be performed using TMR_0 as the upper half and TMR_1
as the lower half (16-bit count mode).
TMR_1 can be used to count TMR_0 compare-match occurrences (compare-match count
mode).
Cascading of TMR_Y and TMR_X *
Operation as a 16-bit timer can be performed using TMR_Y as the upper half and TMR_X
as the lower half (16-bit count mode).
TMR_X can be used to count TMR_Y compare-match occurrences (compare-match count
mode).
