"RESERVED MEMORY" on debug mode

[eabir]

Hello,

While debug the ccs code in MPLAB i got "RESERVED MEMORY" in the watch value area.
What is the general reason ? and how can i fix it?

It happens with PIC16F688 and PIC24H, i assume its general problem in memory definitions?

You don't say where this is.
If you look in the data for the ICD, _all_ chips have some resources that are used by the ICD. Normally at least one interrupt level, a couple of stack levels, a few bytes of RAM, and a few hundred bytes of ROM at the top of the memory space. The amount varies (a little) between chips.
There also is 'reserved memory' in quite a few chips. So (for example) the USB data frame is directly updated by the USB hardware, and is reserved, on USB chips.

Best Wishes

Reserved memory may be also ICD reserved, if you didn't compile with the ICD option in effect, or you are using #device ICD, but CCS C isn't aware of the actual ICD memory allocation. Check the MPLAB ICD related help file and reserve extra memory, if necessary.
