Description
Computes the bit-wise logical AND of first operand (source 1 operand) and the second
operand (source 2 operand) and sets the SF, ZF, and PF status flags according to the
result. The result is then discarded.
Operation
TEMP  SRC1 AND SRC2;
SF  MSB(TEMP);
IF TEMP = 0
THEN ZF  0;
ELSE ZF  1;
FI:
PF  BitwiseXNOR(TEMP[0:7]);
CF  0;
OF  0;
(*AF is Undefined*)
Flags Affected
The OF and CF flags are cleared to 0. The SF, ZF, and PF flags are set according to the
result (see "Operation" above). The state of the AF flag is undefined.
