6.6 Timer/Event Counter
The
μ
PD753208 provides one channel for timer/event counters and two channels for timer counters. Figures
6-5 to 6-7 show the block diagrams. Timer/event counter functions are as follows.
Programmable interval timer operation
Square wave output of any frequency to the PTO0 pin (n = 0 to 2).
Event counter operation (Channel 0 only)
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).
Supplies the shift clock to the serial interface circuit.
Reads the counting status.
The timer/event counter operates in the following four modes as set by the mode register.
