PSC Description
AT90PWM2/3/2B/3B
Figure 16-1. Power Stage Controller 0 or 1 Block Diagram
Note:
The principle of the PSC is based on the use of a counter (PSC counter). This counter is able to
count up and count down from and to values stored in registers according to the selected run-
ning mode.
The PSC is seen as two symetrical entities. One part named part A which generates the output
PSCOUTn0 and the second one named part B which generates the PSCOUTn1 output.
Each part A or B has its own PSC Input Module to manage selected input.
