RISC 16−Bit CPU
MOV[.W] Move source to destination
MOV.B Move source to destination
Syntax MOV src,dst or MOV.W src,dst
MOV.B src,dst
Operation src −> dst
Description The source operand is moved to the destination.
The source operand is not affected. The previous contents of the destination
are lost.
Status Bits Status bits are not affected.
Mode Bits OSCOFF, CPUOFF, and GIE are not affected.
Example The contents of table EDE (word data) are copied to table TOM. The length
of the tables must be 020h locations.
MOV #EDE,R10 ; Prepare pointer
MOV #020h,R9 ; Prepare counter
Loop MOV @R10+,TOM−EDE−2(R10) ; Use pointer in R10 for both tables
DEC R9 ; Decrement counter
JNZ Loop ; Counter ≠ 0, continue copying
...... ; Copying completed
