INTTPnCC1 signal
TPnCCR1 register
TOPn1 pin output
16-bit counter
Count clock
(e) Generation timing of compare match interrupt request signal
Preliminary User’s Manual U17566EE1V2UM00
(INTTPnCC1)
The timing of generation of the INTTPnCC1 signal in the external trigger
pulse output mode differs from the timing of other INTTPnCC1 signals; the
INTTPnCC1 signal is generated when the count value of the 16-bit counter
matches the value of the TPnCCR1 register.
Usually, the INTTPnCC1 signal is generated in synchronization with the
next count up, after the count value of the 16-bit counter matches the value
of the TPnCCR1 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 TOPn1 pin.
