<1> Set each register.
<2> When TMHE1 = 1, the 8-bit timer H1 starts counting.
<3> When TCE51 of the 8-bit timer mode control register 51 (TMC51) is set to 1, the 8-bit timer/event counter 51
<4> After the count operation is enabled, the first compare register to be compared is the CMP01 register. When
<5> When the count value of the 8-bit timer counter H1 and the CMP11 register value match, the INTTMH1 signal is
<6> By performing procedures <4> and <5> repeatedly, a carrier clock is generated.
<7> The INTTM51 signal is synchronized with count clock of the 8-bit timer H1 and output as the INTTM5H1 signal.
<8> Write the next value to the NRZB1 bit in the interrupt servicing program that has been started by the INTTM5H1
<9> When the NRZ1 bit is high level, a carrier clock is output by TOH1 output.

The INTTM5H1 signal becomes the data transfer signal for the NRZB1 bit, and the NRZB1 bit value is
transferred to the NRZ1 bit.
interrupt or after timing has been checked by polling the interrupt request flag. Write data to count the next time
to the CR51 register.
