comparator

[sarasvathi]

how to use comparator of PIC12F675? coz i ve configured one i/p to internal ref. & other to analog i/p from outside.....
im working on unregulated 220VAC, hence how to pump this to comparator i/p ....

also guide me of ...how to awake PIC12F675 from SLEEP state?

so u want to interface the 220 to pic..? there is an application note in microchip website to do it. or simply connect a high value res: considering the max i/p current
