Hi all,

Here is a project using 16F887 controller.ccs c compiler version - 5.015.I am using a little large capacitor at the input 1000uF.This is used so as to prevent error writing to ds1307 RAM area.
When i recycle power if the voltage does not fall below 1V or so then the controller freeze happens and even MCLR does not work.I have brownout fuse turned on at 4.0V.

Please help.

I didn't find the right solution from the Internet.
