12.4 Interrupt Sources
The TMR0, TMR1, and TMRY 8-bit timers can generate three types of interrupt: compare-match
A and B (CMIA and CMIB), and overflow (OVI). TMRX can generate only an ICIX interrupt. An
interrupt is requested when the corresponding interrupt enable bit is set in TCR or TCSR.
Independent signals are sent to the interrupt controller for each interrupt. It is also possible to
activate the DTC by means of CMIA and CMIB interrupts from TMR0, TMR1 and TMRY.
An overview of 8-bit timer interrupt sources is given in tables 12.4 to 12.6.
