Hello Wasim, and welcome to the forum.

 

Does the programming arrangement shown in Fig. 7.1 of the datasheet provide the information that you require?  Application note AN-HK-33 may also be of interest.

 

Regards,

Mac

hi

now the programming is done on the board and booting too

but a problem is still that when i remove the MON-08 CONEECTION from computer then booting is stop .

 

i think this is due to any fault in circuit of RESET,OSCILLATOR,IRQ

i have used

RESET------100K FROM VDDTO 28 PIN 

IRQ--------10K FROM VDD TO 1PIN

CRYSTAL IS 4MHZ BOTH end is pull-down by 22pf capacitor and legs are connected by 440k resistance.........

 

where is fault ?
