9. 8-Bit Timers
Caution
Do not set 16-bit counter mode and compare match count mode simultaneously within the same
group, as the 8TCNT input clock will not be generated and the counters will not operate.
9.4.6
The 8TCNT value can be transferred to TCORB on detection of an input edge on the input
capture/output compare pin (TMIO
can be selected. In 16-bit count mode, 16-bit input capture can be used.

⎯ Set TCORB1 as an 8-bit input capture register with the ICE bit in 8TCSR1.
⎯ Select rising edge, falling edge, or both edges as the input edge(s) for the input capture
⎯ Select the input clock with bits CKS2 to CKS0 in 8TCR1, and start the 8TCNT count.
⎯ Set TCORB3 as an 8-bit input capture register with the ICE bit in 8TCSR3.
⎯ Select rising edge, falling edge, or both edges as the input edge(s) for the input capture
⎯ Select the input clock with bits CKS2 to CKS0 in 8TCR3, and start the 8TCNT count.
