MOV.size (:format) src,dest
[ Operation ]
dest src
[ Function ]
• This instruction transfers
src
to
dest
.
• If
dest is an address register when the size specifier (.size) you selected is (.B), src is zero-expanded to transfer data in
16 bits. If
src is an address register, data is transferred from the address register’s 8 low-order bits.
[ Flag Change ]
Flag
Change
Conditions
S : The flag is set when the transfer resulted in MSB of dest = 1; otherwise cleared.
Z : The flag is set when the transfer resulted in 0; otherwise cleared.
