In order to transfer data from the TQ0CCRm register to the CCRm buffer register, the TQ0CCR1 register
must be written.
After data is written to the TQ0CCR1 register, the value written to the TQ0CCRm register is transferred to
the CCRm buffer register in synchronization with clearing of the 16-bit counter, and is used as the value to
be compared with the 16-bit counter value.

the TQ0CCR1 register).
after the INTTQ0CC0 signal has been generated; otherwise, the value of the CCRm buffer
register may become undefined because the timing of transferring data from the
TQ0CCRm register to the CCRm buffer register conflicts with writing the TQ0CCRm
register.
