Assembly Language Syntax
eZ8 CPU Instruction Notation
PS025011-1010
Table 175. Assembly Language Syntax Example 2
Table 174. Assembly Language Syntax Example 1
For proper instruction execution, eZ8 CPU assembly language syntax requires that the
operands be written as destination and 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
format if you prefer manual program coding or intend to implement your own assembler.
Example 1: If the contents of Registers 43H and 08H are added and the result is stored in
43H, the assembly syntax and resulting object code is as listed in
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 43H and Working
Register R8 are added and the result is stored in 43H, the assembly syntax and resulting
object code is as listed in
