2. When TMHE1 = 1, setting the other bits of the TMHMD1 register is prohibited.
3. In the PWM output mode and carrier generator mode, be sure to set 8-bit timer H compare
4. When the carrier generator mode is used, set so that the count clock frequency of TMH1

clock of the internal oscillator is divided and supplied as the count clock. If the count clock
is the internal oscillation clock, the operation of 8-bit timer H1 is not guaranteed (except
