1.0 DEVICE OVERVIEW
This document contains device-specific information.
Additional information may be found in the PICmicroTM
Mid-Range MCU Family Reference Manual,
(DS33023), which may be obtained from your local
Microchip Sales Representative or downloaded from
the Microchip website. The Reference Manual should
be considered a complementary document to this data
sheet, and is highly recommended reading for a better
understanding of the device architecture and operation
of the peripheral modules.
There are three devices (PIC16C717, PIC16C770 and
PIC16C771) covered by this data sheet. The
PIC16C717 device comes in 18/20-pin packages and
the PIC16C770/771 devices come in 20-pin packages.
The following two figures are device block diagrams of
the PIC16C717 and the PIC16C770/771.

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 asso-
ciated 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 that
peripheral feature section.

Legend:
Note 1:

3:
x = unknown, u = unchanged, q = value depends on condition, - = unimplemented read as '0'.
Shaded locations are unimplemented, read as ‘0’.
The upper byte of the program counter is not directly accessible. PCLATH is a holding register for the PC<12:8> whose
contents are transferred to the upper byte of the program counter.
Other (non Power-up) Resets include external RESET through MCLR and Watchdog Timer Reset.
These registers can be addressed from any bank.
