CHAPTER 6 16-BIT TIMER/EVENT COUNTER P (TMP)
(b) Generation timing of compare match interrupt request signal (INTTPnCC1)
The generation timing of the INTTPnCC1 signal in the one-shot pulse output mode is different from other
INTTPnCC1 signals; the INTTPnCC1 signal is generated when the count value of the 16-bit counter
matches the value of the TPnCCR1 register.

INTTPnCC1 signal
Usually, the INTTPnCC1 signal is generated when the 16-bit counter counts up next time after its count
value matches the value of the TPnCCR1 register.
In the one-shot pulse output mode, however, it is generated one clock earlier. This is because the timing is
changed to match the change timing of the TIOPn1 pin.
