Programmable Output Polarity
The polarity of each macrocell can be active-high or active-low, either to match output signal
needs or to reduce product terms. Programmable polarity allows Boolean expressions to be
written in their most compact form (true or inverted), and the output can still be of the desired
polarity. It can also save “DeMorganizing” efforts.
Selection is through a programmable bit SL1_x which controls an exclusive-OR gate at the output
of the AND/OR logic. The output is active high if SL1_x is 1 and active low if SL1_x is 0.
