PSC2 Distinctive Feature
Output Polarity
Figure 12-2.
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
The polarity “active high” or “active low” of the PSC outputs is programmable. All the timing diagrams in
the following examples are given in the “active high” polarity.
