In order to transfer data from the TPnCCRa register to the CCRa buffer register, the TPnCCR1 register
must be written.
After data is written to the TPnCCR1 register, the value written to the TPnCCRa register is transferred to
the CCRa 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.

specified for the TPnCCR1 register).
register has to be set.
after the INTTPnCC0 signal has been generated; otherwise, the value of the CCRa
buffer register may become undefined because the timing of transferring data from
the TPnCCRa register to the CCRa buffer register conflicts with writing the TPnCCRa
register.
