5-5 Expansion Instructions
The C200HX/HG/HE PCs have more instructions that require function codes
(121) than function codes (100), so some instructions do not have fixed function
codes. These instructions, called expansion instructions, are listed in the follow-
ing table. Default function codes are given for the instructions that have them.
An expansion instruction can be assigned one of 18 function codes using the
Programming Console’s Expansion Instruction Function Code Assignments op-
eration. The 18 function codes are: 17, 18, 19, 47, 48, 60 to 69, 87, 88, and 89.
Refer to 7-2-14 Expansion Instruction Function Code Assignments for details on
assigning function codes.
