Finding some strange issues with using the change on PortB interupts.  I've had it running using B0 interupt, to wake from sleep and its been working just fine.  
   
  I have switches tied to PortB [7:3] so I was thinking of using the switches to wake from sleep, and its partially working.
   
  I have the IOCB set to 0xF0, to enable bits [7:4] for the mask, but there seems to be a documentation issue about the RBIF flag in the INTCON register.
  
page 25 of the data sheet has the INTCON register definition and states:
   
  the bit is set if bits [5:0] have changed states
  the bit is clear if none of [7:4] have changed states
   
  seems to be a conflict there on what exactly does set the interupt flag.
   
  Anyone else ran across the RBIF, assuming it should be [7:4] as that is what other data sheets say.   I have 5 switches, but I can tie one to RB0 and use its interupt as well as the upper 4 bits (if they really are available for that).
