Section 19 Timer Unit (TMU)

There are seven TMU interrupt sources: underflow interrupts and the input capture interrupt when

the input capture function is used. Underflow interrupts are generated on each of the channels, and

input capture interrupts on channel 2 only.

An underflow interrupt request is generated (for each channel) when both the UNF bit and the

interrupt enable bit (UNIE) for that channel are set to 1.

When the input capture function is used and an input capture request is generated, an interrupt is

requested if the ICPF bit in TCR2 is 1 and the input capture control bits (ICPE1 and ICPE0) in

TCR2 are both set to 11.

The TMU interrupt sources are summarized in Table 19.4.
