8.5.3 Interrupt Sources
Each ITU channel can generate a compare match/input capture A interrupt, a compare match/input
capture B interrupt, and an overflow interrupt. In total there are 15 interrupt sources, all
independently vectored. An interrupt is requested when the interrupt request flag and interrupt
enable bit are both set to 1.
The priority order of the channels can be modified in interrupt priority registers A and B (IPRA
and IPRB). For details see section 5, Interrupt Controller.
Table 8-10 lists the interrupt sources.
