Modes of Operation
DT0
Normal Mode
Enhanced Mode
OT0
The simplest mode of operation is the normal mode. See
The active time of PSCOUTn0 is given by the OT0 value. The active time of PSCOUTn1 is given
by the OT1 value. Both of them are 12 bit values. Thanks to DT0 & DT1 to ajust the dead time
between PSCOUTn0 and PSCOUTn1 active signals.
The waveform frequency is defined by the following equation:
The Enhanced Mode uses the previously described method to generate a high resolution
frequency.
