In order to transfer data from the TPnCCRm register to the CCRm buffer register, the TPnCCR1 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
TPnCCR0 register and then set the active level width to the TPnCCR1 register.
To change only the cycle of the PWM waveform, first set the cycle to the TPnCCR0 register, and then write the
same value to the TPnCCR1 register.
To change only the active level width (duty factor) of the PWM waveform, only the TPnCCR1 register has to be
set.
After data is written to the TPnCCR1 register, the value written to the TPnCCRm 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 TPnCCR0 or TPnCCR1 register again after writing the TPnCCR1 register once, do so after the
INTTPnCC0 signal is generated. Otherwise, the value of the CCRm buffer register may become undefined
because the timing of transferring data from the TPnCCRm register to the CCRm buffer register conflicts with
writing the TPnCCRm register.
