dsPIC33FJ32GP202/204 and dsPIC33FJ16GP304
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

dsPIC33FJ32GP202/204 and dsPIC33FJ16GP304
devices provide nonvolatile memory implementation
for device Configuration bits. Refer to Section 25.
“Device Configuration” (DS70194) of 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 Device Configuration register map is shown in

.

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

Note that address 0xF80000 is beyond the user program
memory space. It belongs to the configuration memory
space (0x800000-0xFFFFFF), which can only be
accessed using table reads and table writes. 

This data sheet summarizes the features
of the dsPIC33FJ32GP202/204 and
dsPIC33FJ16GP304 devices. It is not
intended to be a comprehensive refer-
ence source. To complement the informa-
tion in this data sheet, refer to the
“dsPIC33F/PIC24H Family Reference
Manual”. Please see the Microchip web
