here is my code!! what do u think i should do to get my clock to run with a interrupt.!! i got t to run with out and interrupt

ser equ 0000h
MAIN EQU 0300h ;sets the address for the main function
;SERVICE EQU 1000H ;sets the address for the interrupt service routine
;serv2 equ 70f0h
HOURS SET R2 ;Our HOURS variable set to register 2
MINUTES SET R3 ;Our MINUTES variable set to register 3
SECONDS SET R4 ;Our SECONDS variable set to register 4
loop_cnt set R5
TICKS EQU 07Fh ;Our 20th of a second countdown timer
;CRYSTAL EQU 11059200 ;The crystal speed
;TMRCYCLE EQU 12 ;The number of crystal cycles per timer increment
;TMR_SEC EQU 921600 ;CRYSTAL/TMRCYCLE ;The # of timer increments per second
;F20TH_OF_SECOND EQU 46080 ;TMR_SEC/20
RESET_VALUE EQU 19456 ;65536-F20TH_OF_SECOND
PSW DATA 0D0H
TMOD DATA 089H ;TIMER MOD
;TF0 BIT 08DH
TF1 BIT 08FH ;TIMER1 FLAG
TR1 BIT 08EH ;TIMER1 ON/OFF
TL1 DATA 08BH ;TIMER1 LOW BYTE
TH1 DATA 08DH ;TIMER1 HIGH BYTE
TH0 DATA 08CH
TL0 DATA 08AH

TR0 BIT 08CH
EA BIT 0AFH
ET1 BIT 0ABH
ET0 BIT 0A9H
colon equ ':'
LCDC DATA 020H ;LCD CURSOR POSITION (0 TO 1FH)
LCD_RS BIT 090H ;PIN P1.0, H=instruction L=data
LCD_E BIT 091H ;PIN P1.1, enable L=active
LCD_D EQU 0FFF3H ;LCD data port address
ACC DATA 0E0H
XR6 DATA 01EH ;R6 OF BANK#3, SCRATCH MEMORY
XR7 DATA 01FH ;R7 OF BANK#3, SCRATCH MEMORY
DPL DATA 082H
DPH DATA 083H
