I am using a PIC 18F4550 and want to put it into sleep mode to conserve battery life then wake it up using a 'wake up from interrupt'
My question is what I need to do with the I/O lines?
A basic sleep function will put the PIC into a mode which it consumes around 40uA.
However, if other things such as I/O lines, WDT etc are configured correctly, the current consumption can be reduced further.
Any help would be appreciated.

Please help.

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