5.5 TIMER/EVENT COUNTER
The µPD750008 has one timer/event counter channel (channel 0) and one timer counter channel (channel
1). Figures 5-28 and 5-29 show the configuration of these channels.
In this section, the timer/event counter and timer counters are referred to as "timer/event counters." When
you read this section for description of channel 1, take "timer/event counter" as "timer counter."
The timer/event counter has the following functions.
(a) Programmable interval timer operation
(b) Square wave output of any frequency to the PTOn pin.
(c) Event counter operation (Channel 0 only)
(d) Divides the frequency of signal input via the TI0 pin to 1-Nth of the original signal and outputs the
divided frequency to the PTO0 pin (frequency divider operation) (Channel 0 only).
(e) Supplies the serial shift clock to the serial interface circuit (Channel 0 only).
(f) Calls the counting status.
