In this chapter each instruction's syntax, operation, function, selectable src/dest, and flag changes are listed, and description examples and related instructions are shown.

An example illustrating how to read this chapter is shown below.

The syntax of the instruction using symbols. If (:format) is omitted, the assembler chooses the optimum specifier.

MOV.size     src,dest          B,W,L →  (d)

 (a)(b)    (c)

Shows the mnemonic.

Shows the data sizes in which data is handled. The following data sizes may be specified:

.B Byte (8 bits)

.W Word (16 bits)

.L Long word (32 bits)

Some instructions do not have a size specifier.

Shows the operands.

Shows a flag change that occurs after the instruction is executed. The symbols in the table mean the following.

"–" The flag does not change.

" " The flag changes depending on a condition.

Description examples for the instruction.
