MOVEdst,src
MoveData
Description:
Moves data from a specified source (src) to a specified destination (dst) . A list of defined source,
destination spec- ifiers 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 .
StatusFlags:
S, Z (if dst is Acc or AP or APC) C, E (if dst is PSF)
Operation:
