The count operation is enabled by setting the TMHE1 bit to 1. Start 8-bit timer counter H1 by masking one
count clock to count up. At this time, TOH1 output remains inactive (when TOLEV1 = 0).
<2>
When the values of 8-bit timer counter H1 and the CMP01 register match, the TOH1 output level is inverted,
the value of 8-bit timer counter H1 is cleared, and the INTTMH1 signal is output.
<3>
When the values of 8-bit timer counter H1 and the CMP11 register match, the level of the TOH1 output is
returned. At this time, the 8-bit timer counter value is not cleared and the INTTMH1 signal is not output.
<4>
Clearing the TMHE1 bit to 0 during timer H1 operation makes the INTTMH1 signal and TOH1 output inactive.
