ANDAND

11000000 AND Rdest,Rsrc

logic operation instruction

AND

srcdest

[Mnemonic]

AND Rdest,Rsrc

[Function]

Logical AND

Rdest = Rdest & Rsrc;

[Description]

AND computes the logical AND of the corresponding bits of Rdest and Rsrc and puts the result

in Rdest.

The condition bit (C) is unchanged.
