In order to transfer data from the TAAnCCRm register to the CCRm buffer register, the TAAnCCR1 register
must be written.
To change both the cycle and active level width of the PWM waveform at this time, first set the cycle to the
TAAnCCR0 register and then set the active level width to the TAAnCCR1 register.
To change only the cycle of the PWM waveform, first set the cycle to the TAAnCCR0 register, and then
write the same value to the TAAnCCR1 register.
To change only the active level width (duty factor) of the PWM waveform, only the TAAnCCR1 register has
to be set.
After data is written to the TAAnCCR1 register, the value written to the TAAnCCRm register is transferred
to the CCRm buffer register in synchronization with clearing of the 16-bit counter, and is used as the value
compared with the 16-bit counter.
To write the TAAnCCR0 or TAAnCCR1 register again after writing the TAAnCCR1 register once, do so after
the INTTAAnCC0 signal is generated. Otherwise, the value of the CCRm buffer register may become
undefined because the timing of transferring data from the TAAnCCRm register to the CCRm buffer
register conflicts with writing the TAAnCCRm register.
