Example
Move a 16-bit constant 1800h to absolute address-word EDE (lower 64 K)
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 64 K.
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.
