From the
clock generator
The basic interval timer has these functions:
These two channels are almost identical in terms of configuration and function except the count pulse (CP) that
The functions of the timer/event counter include:
• Programmable interval timer operation
• Output of square wave at an arbitrary frequency to PTOn pin
• Event counter operation
• Input of TIn pin signal as external interrupt input signal
• Dividing TIn pin input by N to output to PTOn pin (frequency divider operation)
• Supply of serial shift clock to serial interface circuit (channel 0 only)
• Reading counting status

Remarks : *: Instruction execution
Interval timer operation which generates a reference time interrupt
Watchdog timer application which detects a program runaway
Selects the wait time for releasing the standby mode and counts the wait time
Reads out the count value
