Hello,

I have planned to use a supervisory chip. I also using the reset feature of AT89S52.

Sometime back I had read that if a external reset chip is used as wel as a reset out is generated a resistor ahould be used in between them. But I was unbale to locate that message.


I am planning to power up a LCD using the reset status. As shown below.


I want to know what value should I use for the resistor(R???)??? How do I calculate without damaging the AT89S52 reset pin or the reset out of the supervisory chip.???

Rgds
