Assembly Language Syntax
eZ8 CPU Instruction Notation
PS024314-0308
For proper instruction execution, eZ8 CPU assembly language syntax requires that the
operands be written as ‘destination, source’. After assembly, the object code usually has
the operands in the order ‘source, destination’, but ordering is opcode-dependent. The
following instruction examples illustrate the format of some basic assembly instructions
and the resulting object code produced by the assembler. You must follow this binary for-
mat if you prefer manual program coding or intend to implement your own assembler.
Example 1
If the contents of Registers
assembly syntax and resulting object code is:
Table 103. Assembly Language Syntax Example 1
Example 2
In general, when an instruction format requires an 8-bit register address, that address can
specify any register location in the range 0–255 or, using Escaped Mode Addressing, a
Working Register R0–R15. If the contents of Register
added and the result is stored in
Table 104. Assembly Language Syntax Example 2
See the device-specific Product Specification to determine the exact register file range
available. The register file size varies, depending on the device type.
In the eZ8 CPU Instruction Summary and Description sections, the operands, condition
codes, status flags, and address modes are represented by a notational shorthand that is
