Option List

The

COP244C245C224C225CCOP226C

mask-pro-

grammable options are assigned numbers which corre-

spond with the COP244C224C 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

Caution

The output options available on the COP224C225C226C

and COP244C245C are not the same as those available

on the COP324C325C326C COP344C345C COP424C

425C426C and COP444C445C Options not available on

the COP224C225C226C and COP244C245C are Option

2 value 2 Option 4 value 0 Option 5 value 1 Option 9 value
