each macrocell controls the polarity of the outputin any of the three modes, while theACl bit of each of the macrocells controls the in- put/output configuration. These two global and 16 individual archi- tecture bits define all possible configurations in a GAL16V8Z/ZD. The information given on these architecture bits is only to give a better understanding of the device. Compiler software will trans- parently set these architecture bits from the pin definitions, so the user should not need to directly manipulate these architecture bits.
