Channel 2 has an input capture function.
The procedure for using the input capture function is as follows:
1. Use the TCOE bit in the timer output control register (TOCR) to set the TCLK pin to input
2. Use bits TPSC2–TPSC0 in the timer control register (TCR) to set an internal clock or the on-
3. Use bits IPCE1 and IPCE0 in TCR to specify use of the input capture function, and whether

RTC output clock
In channels 0 to 2, external clock pin (TCLK) input can be selected as the timer clock by
means of the TPSC2–TPSC0 bits in TCR. The detected edge (rising, falling, or both edges) can
be selected with the CKEG1 and CKEG0 bits in TCR.
Figure 12.5 shows the timing for both-edge detection.
In channels 0 to 2, the on-chip RTC output clock can be selected as the timer clock by means
of the TPSC2–TPSC0 bits in TCR. Figure 12.6 shows the timing in this case.
