dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04
devices include several features intended to maximize
application flexibility and reliability, and minimize cost
through elimination of external components. These are:

• Flexible Configuration

• Watchdog Timer (WDT)

• Code Protection and CodeGuard™ Security

• JTAG Boundary Scan Interface

• In-Circuit Serial Programming™ (ICSP™)

• In-Circuit Emulation

• Brown-out Reset (BOR)

dsPIC33FJ06GS101/X02 and dsPIC33FJ16GSX02/X04
devices provide nonvolatile memory implementations
for device Configuration bits. Refer to “Device Config-
uration” (DS70194) in the “dsPIC33F/PIC24H Family
Reference Manual” for more information on this
implementation.

The Configuration bits can be programmed (read
as ‘0’), or left unprogrammed (read as ‘1’), to select
various device configurations. These bits are mapped
starting at program memory location 0xF80000. 

The individual Configuration bit descriptions for the
Configuration registers are shown in 

Note that address, 0xF80000, is beyond the user pro-
gram memory space. It belongs to the configuration
memory space (0x800000-0xFFFFFF), which can only
be accessed using Table Reads and Table Writes.

The device Configuration register map is shown in

 

Note 1: This data sheet summarizes the features

of the dsPIC33FJ06GS101/X02 and
dsPIC33FJ16GSX02/X04 devices. It is
not intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to the
“dsPIC33F/PIC24H Family Reference
Manual”. Please see the Microchip web

“dsPIC33F/PIC24H Family Reference
Manual” sections.

2: Some registers and associated bits

described in this section may not be
available on all devices. Refer to
