uPSD34xx
PSD module
Note:
After PSDsoft Express has accepted and realized the logic from the equations, it
synthesizes the logic statement:
pld_out = ( pld_in_1 # pld_in_2 ) & !pld_in_3;
to be programmed into the GPLD. See the PSDsoft User’s Manual for all the steps.
If a particular OMC output is specified as an internal node and not specified as a port pin
output in PSDsoft Express, then the port pin that is associated with that OMC can be used
for other I/O functions.
