The TAOW register is enabled in programmable output mode.
To change cycles or width of the output waveform, follow the instructions below.
(1)Set the TAiOW bit to 0 (output waveform change disabled). (i = 1, 2, 4)
(2)Write to the TAi register and/or the TAi1 register.
(3)Set the TAiOW bit to 1 (output waveform change enabled).
The updated value is reloaded when the TAiOW bit is 1 (output waveform change enabled) at one cycle
before the rising edge of the TAiOUT output (the falling edge when the TOFSi bit is 1). The value before
the update is reloaded when the TAiOW bit is 0 (output waveform change disabled).
