Option List

The

COP444C445C424C425CCOP426C

mask-pro-

grammable options are assigned numbers which corre-

spond with the COP444C424C 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

IO components using little or no external circuitry

PLEASE FILL OUT THE OPTION TABLE on the next page
