(Note 2)
Note 1: The values of Timer Y Primary and Timer Y Secondary are reloaded to the Timer Y alternately for counting.
Note 2: The count value can be read out by reading the Timer Y Primary even when the secondary period is being
counted.

Nothing is assigned.
When write, set "0". When read, their contents are "0".
Note 1: This bit is automatically cleared to "0" when the output of one-shot waveform is completed. This bit should be set to
"0" by program when the one-shot waveform output is terminated by setting the count start flag to "0" during the
waveform output.
Note 2: This bit is valid only when operating in programmable waveform generation mode.
