Option List
The
grammable options are assigned numbers which corre-
spond with the COP444C 424C pins
The following is a list of options The options are pro-
grammed at the same time as the ROM pattern to provide
the user with the hardware flexibility to interface to various
I O components using little or no external circuitry
