CHAPTER 9 16-BIT TIMER/EVENT COUNTER T (TMT)
In order to transfer data from the TT0CCRn register to the CCRn buffer register, the TT0CCR1 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
TT0CCR0 register and then set the active level width to the TT0CCR1 register.
To change only the cycle of the PWM waveform, first set the cycle to the TT0CCR0 register, and then write
the same value (same as preset value of the TT0CCR1 register) to the TT0CCR1 register.
To change only the active level width (duty factor) of the PWM waveform, only the TT0CCR1 register has
to be set.
After data is written to the TT0CCR1 register, the value written to the TT0CCRn register is transferred to
the CCRn 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 TT0CCR0 or TT0CCR1 register again after writing the TT0CCR1 register once, do so after the
INTTT0CC0 signal is generated. Otherwise, the value of the CCRn buffer register may become undefined
because the timing of transferring data from the TT0CCRn register to the CCRn buffer register conflicts
with writing the TT0CCRn register.
