¾ Example: Modify above example by “INC_YZ” macro.
B0MOV
B0MOV
MOVC
Y, #TABLE1$M
Z, #TABLE1$L
; To set lookup table1’s middle address
; To set lookup table1’s low address.
; To lookup data, R = 00H, ACC = 35H

; Increment the index address for next address.

; To define a word (16 bits) data.
The other example of look-up table is to add Y or Z index register by accumulator. Please be careful if “carry” happen.
¾ Example: Increase Y and Z register by B0ADD/ADD instruction.
