CHAPTER 7 16-BIT TIMER/EVENT COUNTER Q (TMQ)
(e) Generation timing of compare match interrupt request signal (INTTQ0CCb)
The timing of generation of the INTTQ0CCb signal in the external trigger pulse output mode differs from
the timing of INTTQ0CCb signals in other modes; the INTTQ0CCb signal is generated when the count
value of the 16-bit counter matches the value of the CCRb buffer register.

Remark
b = 1 to 3
Usually, the INTTQ0CCb signal is generated in synchronization with the next count up after the count
value of the 16-bit counter matches the value of the CCRb buffer register.
In the external trigger pulse output mode, however, it is generated one clock earlier. This is because the
timing is changed to match the timing of changing the output signal of the TOQ0b pin.
