Example
; Branch if either of Bits 2 and 7 of VarA are non-zero:
AND AL,@VarA,#0x0084
SB Dest,NEQ
; Merge Bits 0,1,2 of VarA with Bits 8,9,10 of VarB and store in
; VarC in bit locations 0,1,2,3,4,5:
AND AL,@VarA,#0x0007
AND AH,@VarB,#0x0700
LSR AH,#5
OR AL,@AH
MOV @VarC,AL

Addressing mode (see Chapter 5)
16-bit immediate constant value
Perform a bitwise AND operation on the 16-bit contents of the location pointed
to by the "loc16" addressing mode with the specified 16-bit immediate
constant. The result is stored in the specified AX register:
AX = [loc16] 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.
OPCODE
; AL = VarA AND 0x0084
; Branch if result is non-zero
; Keep bits 0,1,2 of VarA
; Keep bits 8,9,10 of VarB
; Scale back bits 8,9,10 to bits 3,4,5
; Merge bits
; Store result in VarC
