1. Indexing Through Memory

2. Calculating the Effective Address (EA)
EA = X+ ff
EA = Effective Adderss
X = The content of X or Y register
ff = Offset
Ex. Find the effective address of LDAA $08, X. IX = 1000
EA = $ $08 = $1008

3. Example
Write a program to copy 100 numbers from a table starting at location $0300 to another table starting at location $0400. ORG $ C6 64 LDAB # CE LDX #$ CE LDY #$ A6 00 CON LDAA $00,X 020B 18 A7 00 STAA $00,Y 020E 08 INX 020F INY A DECB F5 BNE CON FE END BRA END
