interupt inconsistancy
 
ok, i was reading over the interupt section in the PIC manual and it listed 8 different interupts on portB: 4 external interupts (RB0-RB3) and 4 i/o ports with interupt-on-change(RB4-RB7). For reference these are on page 110. But everywhere else it says that there are only 6 interupts. Does anyone know whats up with this?

There are 8 interrupts on the chip, but 2 (INT0 and INT1) are being used by IFIs code, so you only have 6 you can use.
