16 / 214 page  PIC16F87/88 DS30487B-page 14 Preliminary 2003 Microchip Technology Inc. 2.2.2 SPECIAL FUNCTION REGISTERS The Special Function Registers are registers used by the CPU and peripheral modules for controlling the desired operation of the device. These registers are implemented as static RAM. A list of these registers is given in Table 2-1. The Special Function Registers can be classified into two sets: core (CPU) and peripheral. Those registers associated with the core functions are described in detail in this section. Those related to the operation of the peripheral features are described in detail in the peripheral feature section.

Shaded locations are unimplemented, read as ‘0’. Note 1: The upper byte of the program counter is not directly accessible. PCLATH is a holding register for PC<12:8>, whose contents are transferred to the upper byte of the program counter. 2: These registers can be addressed from any bank. 3: RA5 is an input only; the state of the TRISA5 bit has no effect and will always read ‘1’. 4: PIC16F88 device only. |
