10.8
TMR_0, TMR_1, and TMR_Y can generate three types of interrupts: CMIA, CMIB, and OVI.
TMR_X can generate an ICIX interrupt. Table 10.5 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.

10.9.1
If a counter clear signal is generated during the T
10.13, clearing takes priority and the counter write is not performed.
