I have a PIC 18F2455 and try to use serval interrupts:

RB0
RB1
RB2

I found the following in the PBP Manual:

INTCON = %10010000

Only I can't find the explanation from this (already take a look in the datasheet)
How can i configure the RB1 and RB2 Interrupts as well.

Maybe a simple question only not for me (at this moment).
