4-4-5 Assigning Expansion Instruction Function Codes
This operation is used to display or change the expansion instructions assigned
to expansion instruction function codes. The assignments can be displayed in
any mode, but can be changed in PROGRAM mode only.

Assign expansion instruction function codes before inputting the program.
The CPM2C will not operate properly if expansion instructions aren’t as-
signed correctly. An expansion instruction can be assigned to one function
code only.
The PC Setup must be set for user-defined expansion instruction assign-
ments. Set bits 8 to 11 of DM 6602 to 1 and turn the PC’s power OFF and
then ON again to enable the new setting.
There is a table on page 77 showing the default function code assignments
in the CPM2C.

4-4-6 Setting and Reading a Program Memory Address
This operation is used to display the specified program memory address and is
possible in any mode.

When inputting a program for the first time, it is generally written to Program
Memory starting from address 000. Because this address appears when the
display is cleared, it is not necessary to specify it.
When inputting a program starting from other than 000 or to read or modify a
program that already exists in memory, the desired address must be desig-
nated.
