In dsPIC33EPXXXGP50X, dsPIC33EPXXXMC20X/
50X,
configuration bytes are implemented as volatile memory.
This
programmed each time the device is powered up.
Configuration data is stored in at the top of the on-chip
program memory space, known as the Flash Configura-
tion Bytes. Their specific locations are shown in
Table
loaded from the Flash Configuration Bytes to the proper
Configuration shadow registers during device Resets.
When creating applications for these devices, users
should always specifically allocate the location of the
Flash Configuration Bytes for configuration data in their
code for the compiler. This is to make certain that pro-
gram code is not stored in this address when the code
is compiled.
The upper 2 bytes of all Flash Configuration Words in
program memory should always be ‘1111 1111 1111
1111’. This makes them 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.
The Configuration Flash Bytes map is shown in

Configuration data is reloaded on all types
of device Resets.
Performing a page erase operation on the
last page of program memory clears the
Flash Configuration Bytes, enabling code
protection as a result. Therefore, users
should avoid performing page erase
operations on the last page of program
memory.
