Hai,

I have a problem in coding for RESET IC(hardware watchdog tps3813i50) which is connected to At89c51ed2.

Even i Toggle WDI pin of Reset IC it is continuously reseting the controller.

Generally, property of Reset IC is, if toggling of WDI Pin stopped, controller should reset. otherwise not.


How can i set exact Delay for toggling the WDI pin.
as per datasheet of Reset IC.

Please help me in writing Delay functions for toggling the WDI pin of reset ic with At89c51ed2 port pin P1^1.

Iam Using KEIL Cx51 for Coding.

if possible send me a sample code to interface RESET IC with At89c51ed2

Thanks & Regards
