Dear Rahul
Jump to a specific point from interrupt(main program here)
Means that change return address from interrupt
so you have only one ways,
that is changing return addreess in ISR.
See the below code:


ORG 00H
LJMP MAIN

ISR:

...
...
...

RETURN:
MOV SP,#9 ;maybe stack is anything first you load 9 on it
POP 7 ;with 2 pop you provide changing return addr
POP 7
MOV R7,#01H ;change upper address in pc
PUSH 7
MOV R7,#00H ;change lower address in pc
PUSH 7
RETI


ORG 100H ;or xxxxH < 1F00H
MAIN:
...
