Morning forum members,

After trying every possible thing (which i could think of) from feedback given by forum I still can not make timer 2 work. Has any member ever used it before, please drop us a line on how to intitialise it. I want to use it as 16bit "Auto-reload mode timer", "counting upwards" and sets TF2 on "overflow" from 0FFFF to 0000. when TF2 is set I want the program to go into ISR, please have a look on my code below. I am very much sure that problem is in initialisation of timer 2 and timer 2 interrupt but what the problem is I can not figure out so I am calling for help.

ORG 00H
LJMP MAIN
ORG 002BH
LJMP T2ISR

MAIN:

MOV P1,#0FFH
MOV T2MOD,#02H    ;initialising timer 2 as auto-reload 16 bit
MOV T2CON,#4CH     timer, counting upwards
MOV IE,#0A0H

MOV RCAP2L,#0F0H  ;1ms timer over flow time
MOV RCAP2H,#0D8H
SETB TR2
SETB TF2          ;forcing interrupt, this does not             
                                      seem to be working
SJMP $

T2ISR:

CLR TR2
CLR TF2
CLR EXF2

CPL P1.6
CPL P1.5

SETB TR2
RETI
 

END

thanks for your time
