BASIC INTERVAL TIMER
The basic interval timer includes the following functions.
It operates as an interval timer which generates reference time interrupts.
It can be applied as a watchdog timer which detects when a program is out of control.
Selects and counts wait times when the standby mode is released.
It reads count contents.

TIMER/EVENT COUNTER
The
μ
PD75117H incorporates two internal timer/event counter channels.
Timer/event counter channel 0 and channel 1 differ only in selectable count pulse (CP) and clock supply function
to serial interface and are the same in other configurations and functions.
Operates as a programmable interval timer.
Outputs square waves in the desired frequency to the PTOn pin.
Operates as an event counter.
Use of TIn pin as an external interrupt input pin.
Divides the TIn pin input into N divisions and outputs it to the PTOn pin (frequency divider operation).
Supplies a serial shift clock to the serial interface circuit. (channel 0 only)
Count status read function.
