TMHMD1
Outputs an arbitrary carrier clock from the TOH1 pin.
<1> Set each register.
<2> When TMHE1 = 1, 8-bit timer H1 starts counting.
<3> When TCE51 of 8-bit timer mode control register 51 (TMC51) is set to 1, 8-bit timer/event counter 51 starts
<4> After the count operation is enabled, the first compare register to be compared is the CMP01 register.
<5> When the count value of 8-bit timer counter H1 and the CMP11 register value match, the INTTMH1 signal
<6> By performing procedures <4> and <5> repeatedly, a carrier clock is generated.
<7> The INTTM51 signal is synchronized with count clock of 8-bit timer H1 and output as the INTTM5H1 signal.
<8> When the NRZ1 bit is high level, a carrier clock is output from the TOH1 pin.
<9> By performing the procedures above, an arbitrary carrier clock is obtained. To stop the count operation,

counting.
When the count value of 8-bit timer counter H1 and the CMP01 register value match, the INTTMH1 signal
is generated, 8-bit timer counter H1 is cleared, and at the same time, the compare register to be compared
with 8-bit timer counter H1 is switched from the CMP01 register to the CMP11 register.
is generated, 8-bit timer counter H1 is cleared, and at the same time, the compare register to be compared
with 8-bit timer counter H1 is switched from the CMP11 register to the CMP01 register.
The INTTM5H1 signal becomes the data transfer signal for the NRZB1 bit, and the NRZB1 bit value is
transferred to the NRZ1 bit.
