PSCR Description
AT90PWM81
Figure 13-1.
The principle of the PSCR is based on the use of a counter (PSCR 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 PSCR is seen as two symmetrical entities. One part named part A which generates the output
PSCOUTr0 and the second one named part B which generates the PSCOUTr1 output.
Each part A or B has its own PSCR Input Module to manage selected input.
