Example 2
In general, when an instruction format requires an 8-bit register address, the 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
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 the notational shorthand listed in
