7. Contention between GR Write and Input Capture: If an input capture signal is generated in the
T2 state of a GR write cycle, the input capture operation has priority and the write to GR is not
performed. Figure 13.58 shows the timing in this case.

8. Notes on Setting Reset Synchronous PWM Mode/Complementary PWM Mode: When bits
CMD1 and CMD0 in TFCR are set, note the following:
A. Write bits CMD1 and CMD0 while TCNT_1 and TCNT_0 are halted.
B. Changing the settings of reset synchronous PWM mode to complementary PWM mode or
vice versa is disabled. Set reset synchronous PWM mode or complementary PWM mode
after the normal operation (bits CMD1 and CMD0 are cleared to 0) has been set.
