Section 9 8-Bit Timers
9.5
9.5.1
The 8-bit timer unit can generate three types of interrupt: compare match A and B (CMIA and
CMIB) and overflow (TOVI). Table 9.5 shows the interrupt sources and their priority order. Each
interrupt source is enabled or disabled by the corresponding interrupt enable bit in 8TCR. A
separate interrupt request signal is sent to the interrupt controller by each interrupt source.
Table 9.5
For compare match interrupts CMIA1/CMIB1 and CMIA3/CMIB3 andg the overflow interrupts
(TOVI0/TOVI1 and TOVI2/TOVI3), one vector is shared by two interrupts.
Table 9.6 lists the interrupt sources.
