10.5.3 Interrupt Sources and DMA Controller Activation
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.
Compare match/input capture A interrupts in channels 0 to 3 can activate the DMA controller
(DMAC). When the DMAC is activated a CPU interrupt is not requested.
Table 10-10 lists the interrupt sources.

Note: * The priority immediately after a reset is indicated. Inter-channel priorities can be changed
by settings in IPRA and IPRB.
