MOV loc16, #0
6-166
MOV loc16, #0 Clear 16-bit Location
SYNTAX OPTIONS OPCODE OBJMODE RPT CYC
MOV loc16, #0 0010 1011 LLLL LLLL X Y N+1
Operands loc16 Addressing mode (see Chapter 5)
#0 Immediate constant value of zero
Description Load the location pointed to by the “loc16” addressing mode with the value
0x0000:
[loc16] = 0x0000;
Flags and
Modes
N
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.
Z
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.
Repeat This instruction is repeatable. If the operation is follows a RPT instruction,
then it will be executed N+1 times.
Example
; Initialize the contents of Array1 with zero:
; int16 Array1[N];
; for(i=0; i < N; i++)
; Array1[i] = 0;
MOVL XAR2,#Array1 ; XAR2 = pointer to Array1
RPT #(N−1) ; Repeat next instruction N times
||MOV *XAR2++,#0 ; Array1[i] = 0,
; i++
