18.4.2
Channel 2 has an input capture function.
The procedure for using the input capture function is as follows:
1. Use bits TPSC2 to TPSC0 in TCR2 to set an internal clock as the timer operating clock.
2. Use bits IPCE1 and IPCE0 in TCR2 to specify use of the input capture function, and whether
3. Use bits CKEG1 and CKEG0 in TCR2 to specify whether the rising or falling edge of the
When input capture occurs, the TCNT2 value is set in TCPR2 only when the ICPF bit in TCR2 is
0. A new DMAC transfer request is not generated until processing of the previous request is
finished.
Figure 18.7 shows the operation timing when the input capture function is used (with TCLK rising
edge detection).
interrupts are to be generated when this function is used.
TCLK pin is to be used to set the TCNT value in TCPR2.
