<1> When TMHE1 = 0 and TCE51 = 0, 8-bit timer counter H1 operation is stopped.
<2> When TMHE1 = 1 is set, 8-bit timer counter H1 starts a count operation. At that time, the carrier clock is held
<3> When the count value of 8-bit timer counter H1 matches the CMP01 register value, the first INTTMH1 signal
<4> When the count value of 8-bit timer counter H1 matches the CMP11 register value, the INTTMH1 signal is
<5> When the INTTM51 signal is generated, it is synchronized with 8-bit timer H1 count clock and output as the
<6> The INTTM5H1 signal becomes the data transfer signal for the NRZB1 bit, and the NRZB1 bit value is
<7> When NRZ1 = 0 is set, the TOH1 output becomes low level.
