Accumulator high (AH) or accumulator low (AL) register
Addressing mode (see Chapter 5)
Perform a bitwise AND operation on the contents of the specified AX register
with the 16-bit contents of the location pointed to by the "loc16" addressing
mode. The result is stored in the AX register:
AX = AX AND 16bit;
The load to AX is tested for a negative condition. If bit 15 of AX is 1, then the
negative flag bit is set; otherwise it is cleared.
The load to AX is tested for a zero condition. The zero flag bit is set if the
operation generates AX = 0; otherwise it is cleared
This instruction is not repeatable. If this instruction follows the RPT
instruction, it resets the repeat counter (RPTC) and executes only once.
