Eighteen address lines are bonded out (A15:0, A16:0, or A17:0 selected during chip configuration).
2.
Data in this area is accessible by indirect addressing only.
3.
Eight addresses at the top of all external memory maps are reserved for current and future device
configuration byte information.
4.
This reserved area returns unspecified values and writes no data.
5.
Data is accessible by direct and indirect addressing.
6.
Data is accessible by direct, indirect, and bit addressing.
7.
The special function registers (SFRs) and the register file have separate internal address spaces.
8.
