PSC Description
AT90PWM81
Figure 13-1.
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 running mode.
The PSC is seen as two symmetrical 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.
