6.7 Timer/Event Counter
The
μ
PD753017A has three channels of timer/event counter. The timer/event counter has the following
functions.
Programmable interval timer operation
Square wave output of any frequency to the PTOn pin (n = 0, 1)
Event counter operation
Divides the frequency of signal input via the TIn pin to 1-Nth of the original signal and outputs the divided
frequency to the PTOn pin (frequency division operation).
Supplies the shift clock to the serial interface circuit (channel 0 only).
Calls the count value.
The timer/event counter operates in the following four modes as set by the mode register.
