Notation and Layout of Instruction Descriptions
Instructions are described in groups by function. Refer to Appendix A List of Instructions by Function
Code for a list of instructions by mnemonic that lists the page number in this section for each instruc-
tion.
The description of each instruction is organized as described in the following table.
Item Contents
Instruction Indicates the name of the instruction. Example: MOVE BIT
Mnemonic Indicates the mnemonic.
Example: MOVB(082)
Variations Differentiation
@ Instruction that differentiates when the execution condition turns ON.
% Instruction that differentiates when the execution condition turns OFF.
Immediate refreshing
! Refreshes data in the I/O area specified by the operands or the Special I/O Unit words when
the instruction is executed.
Function code Indicates the function code.
Function The basic purpose of the instruction is described after the section heading.
Symbol The ladder symbol used to represent the instruction on the CX-Programmer is shown, as in the exam-
ple for the MOVE BIT instruction given below. The name of each operand is also provided with the lad-
der symbol.
Applicable Program Areas The program areas in which the instruction can be used are specified. “OK” indicates the areas in
which the instruction can be used.
Operands Indicates a description of the operand, the data type, and the size.
Where necessary, the meaning of words and bits used in specific operands, such as control words, is
given.
Operand Specifications The memory areas addresses that can be used each operand are listed in a table like the following
one. The letters used in the column headings on the above are the same as those used in the ladder
symbol. “---” is used to indicate when an area cannot be specific for an operand.
