OE Generator
There is one output enable (OE) generator per PAL block that generates two product-term driven
output enables. Each I/O cell is simply an output buffer. Each I/O cell within the PAL block can
choose to be permanently enabled, permanently disabled, or choose one of the two product term
output enables per PAL block (Figure 6).
