51 starts counting.
When the count value of the 8-bit timer counter H1 and the CMP01 register value match, the INTTMH1
signal is generated, the 8-bit timer counter H1 is cleared. At the same time, the compare register to be
compared with the 8-bit timer counter H1 is switched from the CMP01 register to the CMP11 register.

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