(5) Output control circuit
(6) Prescaler
(7) Selector
It is possible to invert the timer output when the compare register (CR00, CR01) register contents and the contents of the
timer register (TM0) match. A square wave can be output from the timer output pins (TO0/TO1) in accordance with the
setting of the low-order 4 bits of the timer output control register (TOC). At this time, PWM output or PPG output can be
performed according to the specification of capture/compare control register 0 (CRC0).
In addition, one-shot pulse output can also be performed by means of a software trigger.
Timer output can be disabled/enabled by means of the TOC. When timer output is disabled, a fixed level is output to the
TO0 and TO1 pins (the output level is set by the TOC).
The prescaler generates the count clock from the internal system clock. The clock generated by this prescaler is selected
by the selector, and is used as the count clock by the timer register 0 (TM0) to perform count operations.
The selector selects a signal resulting from dividing the internal clock or the edge detected by the edge detection circuit as
the count clock of timer register 0 (TM0).
