12.5
There are two sources of TMU interrupts: underflow interrupts (TUNI) and interrupts when using
the input capture function (TICPI2).
12.5.1
The UNF bit is set to 1 when the TCNT underflows. Figure 12.7 shows the timing.
12.5.2
The status flag can be cleared by writing 0 from the CPU. Figure 12.8 shows the timing.
