(1) 8-bit timer H compare register 01 (CMP01)
(2) 8-bit timer H compare register 11 (CMP11)
at which the count value and the compare value before the rewrite match. If the timing at which the count value and
compare value match conflicts with the timing of the writing from the CPU to CMP11, the compare value after the
rewrite takes effect at the timing at which the next count value and the compare value before the rewrite match.

CMP11 can be rewritten during timer count operation.
If the CMP11 value is rewritten during timer operation, the compare value after the rewrite takes effect at the timing
Caution In the PWM output mode, be sure to set CMP11 when starting the timer count operation (TMHE1
