17.4.2
Timing of Interrupt Flag Setting to 1 at Compare Match
The interrupt flag is set to 1 by a compare match signal generated when values of TCORA and TCORB and that of
TCNT match.
The compare match signal is generated at the last state in which the match is true, just before the timer counter is updated.
Therefore, when values of TCORA and TCORB and that of TCNT match, the compare match signal is not generated
until the next TCNT clock input.
Figure 17.7 shows this timing. For details on the corresponding interrupt vector number, see section 10, Interrupt Control
Unit (ICU) and table 17.6, TMR Interrupt Sources.
