(b) Generation timing of compare match interrupt request signal (INTTQ0CCb)
INTTQ0CCb signal
TQ0CCRb register
The generation timing of the INTTQ0CCb signal in the one-shot pulse output mode is different from
INTTQ0CCb signals in other modes; the INTTQ0CCb signal is generated when the count value of the 16-
bit counter matches the value of the TQ0CCRb register.
TOQ0b pin output
Note Actually, the timing is delayed by one operating clock (f
Remark
Usually, the INTTQ0CCb signal is generated when the 16-bit counter counts up next time after its count
value matches the value of the TQ0CCRb 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 TOQ0b pin.
