TIMER/PULSE GENERATOR

The PD75216A incorporates one channel of timer/pulse generator which can be used as a timer or a pulse
generator. The timer/pulse generator has the following functions.
(a)
Functions available in the timer mode
8-bit interval timer operation (IRQTPG generation) enabling the clock source to be varied at 5 levels
Square wave output to PPO pin
(b)
Functions available in the PWM pulse generation mode
14-bit accuracy PWM pulse output to the PPO pin (Used as a digital-to-analog converter and applicable
to tuning)

Fixed time interval (
= 7.81 ms : at 4.19 MHz operation) interrupt generation
f
XX
If pulse output is not necessary, the PPO pin can be used as a 1-bit output port.
Note
If the STOP mode is set while the timer/pulse generator is in operation, miss-operation may result.
To prevent that from occurring, preset the timer/pulse generator to the stop state using its mode
register.
