23.0
dsPIC33F devices include several features intended to
maximize application flexibility and reliability, and mini-
mize 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
23.1
The Configuration bits can be programmed (read as
‘0’), or left unprogrammed (read as ‘1’), to select vari-
ous device configurations. These bits are mapped
starting at program memory location 0xF80000.

On the dsPIC33F General Purpose Family devices (dsPIC33FJXXXGPXXX), these bits are reserved (read as ‘1’ and
must be programmed as ‘1’).
These reserved bits read as ‘1’ and must be programmed as ‘1’.
Unimplemented bits are read as ‘0’.
This reserved bit is a read-only copy of the GCP bit.
This data sheet summarizes the features
of this group of dsPIC33F devices. It is not
intended to be a comprehensive reference

The device Configuration register map is shown in
Table 23-1.
The individual Configuration bit descriptions for the
FBS, FSS, FGS, FOSCSEL, FOSC, FWDT, FPOR and
FICD Configuration registers are shown in Table 23-2.
Note that address 0xF80000 is beyond the user program
memory space. In fact, it belongs to the configuration
memory space (0x800000-0xFFFFFF) which can only be
accessed using table reads and table writes.
The upper byte of all device Configuration registers
should always be ‘1111
appear to be NOP instructions in the remote event that
their locations are ever executed by accident. Since
Configuration bits are not implemented in the
corresponding locations, writing ‘1’s to these locations
has no effect on device operation.
To prevent inadvertent configuration changes during
code execution, all programmable Configuration bits
are write-once. After a bit is initially programmed during
a power cycle, it cannot be written to again. Changing
a device configuration requires that power to the device
be cycled.
