Example
; Initialize all Array1 elements with the value 0xFFFF:
MOV

RPT
|| MOV
1001 011A LLLL LLLL
Addressing mode (see Chapter 5)
Accumulator high (AH) or accumulator low (AL) register
Load the addressed location pointed to by the "loc16" addressing mode with
the 16-bit content of the specified AX register (AH or AL):
[loc16] = AX;
If (loc16 = @AX), then the load to AX is tested for a negative condition. The
negative flag bit is set if bit 15 of AX is 1, 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.
If this operation follows a RPT instruction, then it will be executed N+1 times.
The state of the N and Z flags will reflect the final result.
