12.5 Functional Description
12.5.1 Waveform Cycles
The waveform generated by PSC can be described as a sequence of two waveforms.
The first waveform is relative to PSCOUTn0 output and part A of PSC. The part of this waveform
is sub-cycle A in Figure 12-4 on page 105.
The second waveform is relative to PSCOUTn1 output and part B of PSC. The part of this wave-
form is sub-cycle B in Figure 12-4 on page 105.
The complete waveform is ended with the end of sub-cycle B. It means at the end of waveform
B.
