... GAL26V12 OUTPUT LOGIC MACROCELL (OLMC) OUTPUT LOGIC MACROCELL CONFIGURATIONS Each of the Macrocells of the GAL26V12 has two primary func- tional modes: registered, and combinatorial I/O. The modes and the output polarity are set by four architecture bits (S0, S1, S2 and S3), which are normally controlled by the logic compiler. Each of these two primary modes, and the bit settings required to enable them, are described below and on the following page ...
