11.8

Interrupt Sources

The TMR0, TMR1, and TMRY can generate three types of interrupts: CMIA, CMIB, and OVI.
The TMRX can generate four types of interrupts: CMIA, CMIB, OVI, and ICIX. Table 11.3
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.
