Instruction Set
150
In general, whenever an instruction format requires an 8-bit register address, that address
can specify any register location in the range 0–255 or a Working Register R0–R15. If, in
the above example, register
08h
is a Working Register, the assembly syntax and resulting
object code would be:
Refer to the device product specification to determine the exact register file range avail-
able. The register file size varies by device type.
