<1> When TMHE1 = 0 and TCE51 = 0, the 8-bit timer counter H1 operation is stopped.
<2> When TMHE1 = 1 is set, the 8-bit timer counter H1 starts a count operation. At that time, the carrier clock
<3> When the count value of the 8-bit timer counter H1 matches the CMP01 register value, the first INTTMH1 signal
<4> When the count value of the 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 the 8-bit timer H1 count clock and is output as the
<6> A carrier signal is output at the first rising edge of the carrier clock if NRZ1 is set to 1.
