12 / 200 page  PIC16F87X DS30292A-page 12 Preliminary © 1998 Microchip Technology Inc. 2.2 Data Memory Organization The data memory is partitioned into multiple banks which contain the General Purpose Registers and the Special Function Registers. Bits RP1 and RP0 are the bank select bits. = 00 → Bank0 = 01 → Bank1 = 10 → Bank2 = 11 → Bank3 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 General Purpose Registers, implemented as static RAM. All implemented banks contain special function registers. Some “high use” special function registers from one bank may be mirrored in another bank for code reduction and quicker access. 2.2.1 GENERAL PURPOSE REGISTER FILE The register file can be accessed either directly, or indi- rectly through the File Select Register FSR. RP1 RP0 (STATUS<6:5>) Note: EEPROM Data Memory description can be found in Section 7.0 of this Data Sheet |
