12.8 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 12.5 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.
The CMIA and CMIB interrupts can be used as DTC activation interrupt sources.
