[ 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.
