MOVE dst, src Move Data

Description: Moves data from a specified source (src) to a specified destination (dst). A list of defined source,

destination specifiers is given in the table below. Also, since src can be either 8-bit (byte) or 16-

bit (word) data, the rules governing data transfer are also explained below in the encoding

section.

Status Flags: S, Z (if dst is Acc or AP or APC)

C, E (if dst is PSF)

Operation: dst  src

Encoding: 15 0
