Generates the INTTMH1 signal repeatedly at the same interval.
<1> Set each register.
<2> Count operation starts when TMHE1 = 1.
<3> When the values of 8-bit timer counter H1 and the CMP01 register match, the INTTMH1 signal is generated
<4> Subsequently, the INTTMH1 signal is generated at the same interval. To stop the count operation, clear
