8-bit timer counter H1
<1> The count operation is enabled by setting the TMHE1 bit to 1. Start 8-bit timer counter H1 by masking one
<2> When the values of 8-bit timer counter H1 and the CMP01 register match, the TOH1 output level is inverted,
<3> When the values of 8-bit timer counter H1 and the CMP11 register match, the level of the TOH1 output is
<4> Clearing the TMHE1 bit to 0 during timer H1 operation makes the INTTMH1 signal and TOH1 output inactive.
