The ITU has two types of interrupts: input capture/compare match interrupts, and overflow
interrupts.
10.5.1
Timing of Setting of IMFA and IMFB at Compare Match
IMFA and IMFB are set to 1 by a compare match signal generated when TCNT matches a general
register (GR). The compare match signal is generated in the last state in which the values match
(when TCNT is updated from the matching count to the next count). Therefore, when TCNT
matches a general register, the compare match signal is not generated until the next timer clock
input. Figure 10.57 shows the timing of the setting of IMFA and IMFB.
