9.5.3 Interrupt Sources
Each 16-bit timer 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 nine interrupt sources
of three kinds, all independently vectored. An interrupt is requested when the interrupt request flag
are set to 1.
The priority order of the channels can be modified in interrupt priority registers A (IPRA). For
details see section 5, Interrupt Controller.
Table 9.6 lists the interrupt sources.
