23.7 Rising Edge and Reverse Dead Band
In Half Bridge mode, the rising edge dead band delays the turn-on of the CWGxA output after the rising edge of the CWG data input. In Full Bridge mode, the reverse dead-band delay is only inserted when changing directions from Forward mode to Reverse mode, and only the modulated output, CWGxB, is affected.
The CWGxDBR register determines the duration of the dead-band interval on the rising edge of the input source signal. This duration is from 0 to 64 periods of the CWG clock. The following figure illustrates different dead-band delays for rising and falling CWG Data events.
Dead band is always initiated on the edge of the input source signal. A count of zero indicates that no dead band is present.
If the input source signal reverses polarity before the dead-band count is completed, then no signal will be seen on the respective output.
