Is this possible if we use hard reset (Logic 1 Pulse with some delay) by using ISR and one Port Pin Connected to RESET Pin? so that Controller can RESET itself by Applying RESET signal by ISR. I mean Software *** Hardware RESET!
AT89S52 can be reset with logic high for 2 machine cycles to RESET PIN. I used Proteus VSM 7.1 and it shows RESET... Reset itself by ISR and Port Pin
delay(); RESET_Port_Pin=1; //Soft Reset to uC by Port Pin delay(); RESET_Port_Pin=0; delay();
But in Actual Circuit this Doesn't works. Without any chip it could be done or not? I think momentry latching of some type will help? Please help!
"By the way,the watchdog will not help you generate a intended RESET."
This is quite an unusual and surprising notion to those of us who have been using the watchdog to generate a reset.
Please elaborate how you have come to this conclusion!
