PIC16C925/926
2.2
The data memory is partitioned into four banks which
contain the General Purpose Registers and the Special
Function Registers. Bits RP1 and RP0 are the bank
select bits.
The lower locations of each Bank are reserved for the
Special Function Registers. Above the Special Func-
tion Registers are General Purpose Registers imple-
mented as static RAM. All four banks contain special
function registers. Some “high use” special function
registers are mirrored in other banks for code reduction
and quicker access.

2.2.1
The register file can be accessed either directly, or indi-
rectly
(Section 2.6).
The following General Purpose Registers are not phys-
ically implemented:
• F0h-FFh of Bank 1
• 170h-17Fh of Bank 2
• 1F0h-1FFh of Bank 3
These locations are used for common access across
banks.
