2.2
The data memory is partitioned into multiple banks that
contain the General Purpose Registers and the Special
Function Registers. Bits RP1 (Status<6>) and RP0
(Status<5>) are the bank select bits.

Each bank extends up to 7Fh (128 bytes). The lower
locations of each bank are reserved for the Special
Function Registers. Above the Special Function Regis-
ters are the General Purpose Registers, implemented
as static RAM. All implemented banks contain SFRs.
Some “high use” SFRs from one bank may be mirrored
in another bank for code reduction and quicker access
(e.g., the Status register is in Banks 0-3).
2.2.1
The register file can be accessed either directly or
indirectly through the File Select Register, FSR.
