Nice example.

For how many input bits this can be used , like can the same be used for 100 LEDS?

Mr.Michael Karas why the following is used and cannot understand the explaination as you have given in your answer at that link;


CALL_TABLE:
CLR C ;
RLC A ; multiply * 2 for word access
MOV R0, A ; save a copy of index
INC A ; increment index to the hig byte
MOVC A, @A+DPTR ; low byte
PUSH ACC ; onto stack
MOV A, R0
MOVC A, @A+DPTR ; high byte
PUSH ACC ; onto stack
RET ; direct branch to the subroutine

END
