Option List
The COP244C 245C 224C 225C COP226C mask-pro-
grammable options are assigned numbers which corre-
spond with the COP244C 224C 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
Caution
The output options available on the COP224C 225C 226C
and COP244C 245C are not the same as those available
on the COP324C 325C 326C COP344C 345C COP424C
425C 426C and COP444C 445C Options not available on
the COP224C 225C 226C and COP244C 245C are Option
2 value 2 Option 4 value 0 Option 5 value 1 Option 9 value
0 Option 17 value 1 Option 30 Dual Clock all values Op-
tion 32 Microbus all values Option 33 values 2 4 and 6
