4.6.2.32 MOV
MOV[.W] Move source word to destination word
MOV.B Move source byte to destination byte
Syntax
MOV src,dst or MOV.W src,dst
MOV.B src,dst
Operation src → dst
Description The source operand is copied to the destination. The source operand is not affected.
Status Bits N: Not affected
Z: Not affected
C: Not affected
V: Not affected
Mode Bits OSCOFF, CPUOFF, and GIE are not affected.
Example Move a 16-bit constant 1800h to absolute address-word EDE (lower 64KB)
MOV #01800h,&EDE ; Move 1800h to EDE
Example The contents of table EDE (word data, 16-bit addresses) are copied to table TOM. The
length of the tables is 030h words. Both tables reside in the lower 64KB.
MOV #EDE,R10 ; Prepare pointer (16-bit address)
Loop MOV @R10+,TOM-EDE-2(R10) ; R10 points to both tables.
; R10+2
CMP #EDE+60h,R10 ; End of table reached?
JLO Loop ; Not yet
... ; Copy completed
Example The contents of table EDE (byte data, 16-bit addresses) are copied to table TOM. The
length of the tables is 020h bytes. Both tables may reside in full memory range, but must
be within R10 ± 32 K.
MOVA #EDE,R10 ; Prepare pointer (20-bit)
MOV #20h,R9 ; Prepare counter
Loop MOV.B @R10+,TOM-EDE-1(R10) ; R10 points to both tables.
; R10+1
DEC R9 ; Decrement counter
JNZ Loop ; Not yet done
... ; Copy completed
