8-bit timer counter Hn
<1> The count operation is enabled by setting the TMHEn bit to 1. Start the 8-bit timer counter Hn by masking
<2> When the values of the 8-bit timer counter Hn and the CMP0n register match, an active level is output. At
<3> When the values of the 8-bit timer counter Hn and the CMP1n register match, an inactive level is output. At
<4> Clearing the TMHEn bit to 0 during timer Hn operation sets the INTTMHn signal to the default and PWM

(TOLEVn = 1)
Count clock
one count clock to count up. At this time, PWM output outputs an inactive level.
this time, the value of the 8-bit timer counter Hn is cleared, and the INTTMHn signal is output.
this time, the 8-bit timer counter value is not cleared and the INTTMHn signal is not output.
