Channel 2 has an input capture function (figure 12.7). When using the input capture function, set
the TCLK pin to input mode with the TCOE bit in the timer output control register (TOCR) and
set the timer operation clock to internal clock or on-chip RTC clock with the TPCS2 to TPCS0
bits in the timer control register (TCR_2). Also, designate use of the input capture function and
whether to generate interrupts on using it with the IPCE1 and IPCE0 bits in TCR_2, and designate
the use of either the rising or falling edge of the TCLK pin to set the timer counter (TCNT_2)
value into the input capture register (TCPR_2) with the CKEG1 and CKEG0 bits in TCR_2.
The input capture function cannot be used in standby mode.
