PSC2 Distinctive Feature
Figure 16-2. PSC2 Block Diagram
Note:
PSC2 has two supplementary outputs PSCOUT22 and PSCOUT23. Thanks to a first selector
PSCOUT22 can duplicate PSCOUT20 or PSCOUT21. Thanks to a second selector PSCOUT23
can duplicate PSCOUT20 or PSCOUT21.
The Output Matrix is a kind of 2*2 look up table which gives the possibility to program the output
values according to a PSC sequence
