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
