Addressing mode (see Chapter 5)
AR0 to AR7, lower 16 bits of auxiliary registers
Load the contents of the 16-bit location with ARn:
[loc16] = ARn;
If(loc16 = @ARn), then only the lower 16 bits of the selected auxiliary register
is modified. The upper 16 bits is unchanged.
If (loc16 = @AX), then the load to AX is tested for a negative condition. Bit-15
of the AX register is the sign bit, 0 for positive, 1 for negative. The negative
flag bit is set if the operation on the AX register generates a negative value,
otherwise it is cleared.
If (loc16 = @AX), then the load to AX is tested for a zero condition. The bit is
set if the result of the operation on the AX register generates a 0 value,
otherwise it is cleared
This instruction is repeatable. If the operation is follows a RPT instruction,
then it will be executed N+1 times.

; Load AL with the 16-bit contents of
; AR3. If bit 15 of AL is 1, set the
; N flag, else clear it.
; If AL is 0, set the Z flag.
; Load AR4 with the value in AR3.
; Upper 16 bits of XAR4 are
; unchanged.
; Push the contents of AR3 onto the
; stack. Post increment SP.
; Store contents of AR4 into location
; specified by XAR4. Post-increment
; the contents of XAR4.
; Pre-decrement the contents of XAR5.
; Store the contents of AR5 into the
; location specified by XAR5.
