PIc is 18F67k22 - My typo on Thread header

The datasheet talks about an extended memory map when using external memory bus

does PBP3 allow for an extended memory when used to be compiled for this chip , and if so is what is required

I am sure if i try and use more mem then 4k when setting up variables it would not work. unless i told PBP some how that external memory has been added and can use it for this chip/ application and then compile ??

Any information on this would be useful as i would like to use more memory for this application both in active memory and perhaps program memory than the base chip , which is designed to allow this to happen

Cheers
