6.7 Timer/Event Counter
The PD753017 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
• Event counter operation
• Divides the frequency of signal input via the TIn pin to 1-Nth of the original signal and outputs the divided
• Supplies the serial shift clock to the serial interface circuit.
• Calls the counting status.
frequency to the PTOn pin (frequency divider operation).
The timer/event counter operates in the following four modes as set by the mode register.
Mode
8-bit timer/event counter mode
PWM pulse generator mode
16-bit timer/event counter mode
Carrier generator mode
Note Used for gate control signal generation
