Hello Saran

The best you can do is to do the following at the start of your program.

Write to the TrisB register to configure bit 0 as an output.

trisb = 0x00;

Write to the PortB register to output a 1 to the pin.

portb = 0x01;

You cannot have the pin set to 1 as standard on power on because all I/O pins are configured to be inputs as standard.
