[ Operation ]
dest src
B , W
UIOBSZDC
Conditions
S : The flag is set when the operation resulted in MSB = 1; otherwise cleared.
Z : The flag is set when the operation resulted in 0; otherwise cleared.
This instruction transfers
src
to
dest
in an extended area.
If
src
is an A0 or A1 when the size specifier (.size) you selected is (.B), operation is performed on the
8 low-order bits of A0 or A1. However, the flag changes depending on the A0 or A1 status (16 bits)
before the operation is performed.
