13.8 Interrupt Sources
TMR_0, TMR_1, and TMR_Y can generate three types of interrupts: CMIA, CMIB, and OVI.
TMR_X can generate four types of interrupts: CMIA, CMIB, OVI, and ICIX. Table 13.6 shows
the interrupt sources and priorities. Each interrupt source can be enabled or disabled independently
by interrupt enable bits in TCR or TCSR. Independent signals are sent to the interrupt controller
for each interrupt.
