... This allows each output to be individually configured as either active high or active low. Output Logic Macrocell Configurations Each of the Macrocells of the GAL18V10 has two primary functional modes: registered, and combinatorial I/O. The modes and the output polarity are set by two bits (SO and S1), which are normally controlled by the logic compiler ...

... The signature data is always available to the user independent of the state of the security cell. Security Cell A security cell is provided in every GAL18V10 device to prevent unauthorized copying of the array patterns. Once programmed, this cell prevents further read access to the functional bits in the device ...

... OUTPUT REGISTER ACTIVE HIGH OUTPUT REGISTER Circuitry within the GAL18V10 provides a reset signal to all reg- isters during power-up. All internal registers will have their Q outputs set low after a specified time (tpr, 1µs MAX result, the state on the registered output pins (if they are enabled) will be either high or low on power-up, depending on the programmed polarity of the output pins ...
