4.7.4
The generic method described in this paragraph can be applied to any of the SX1504, SX1505 or SX1506.
Example: We want to implement an AND gate between I/O[0] and IO[1] on SX1505
Rev 2 – 30
1. Identify in the tables above the RegPLDMode setting to be programmed.
2. Fill corresponding RegPLDTableX with the wanted truth table.
What we need corresponds to the second line of the SX1505 PLD Table => RegPLDMode = “xx00xx01”
As mentioned in RegPLDMode description, using PLD 2-to-1 mode on I/0[0-2] implies to fill the truth
table located in RegPLDTable0(3:0)
