// Use:
// gpr0 is not available for indirect memory access
// To work around this, we will try to force all banked accesses into gpr0// 
// To do this, use the 'udata' pragma like so:
//
// #pragma udata forcebanked MyVar
// unsigned char MyVar;
//
// Scalar variables will always use banked access, so they should be assigned to gpr0 as above
// Aggregate types (arrays, structs) should not be stored here as they will use indirect addressing
//
