BOR settings

[adrian]

Anybody know how to view the BOR calibration setting? They are at address 2008h i.e one above the configuration register at 2007h which can be viewed in MPLab.

Could you do something like what i do for RCREG register
#BYTE RCREG=0XFAE


so yours


#BYTE BOR=0x2008 //note no semicolin

I'm sorry. I don't use mplab.

First thing to understand, is that what a 'development enviroment' can do, does not necessarily correspond to what a chip can actually do.
The memory area corresponding to the calibration registers, is not readable on a chip, _unless_ this is a flash programmable type, which supports access of this type. On these chips, the 'read_program_memory' function, will allow these bytes to be read. The fact you are talking about the BOR fuses being at 0x2008, implies this is a 16 family chip, and on a device like the 16F688, these fuses are accessible using this function.

OK I don't think I explained my self very well. I do not want the 'chip' to read it's own calibration register. I was wondering if within the 'development enviroment' , the ICD2 programmer could load the calibration data into MPLab to be viewed, and if so how?

'Programmer', 'read', then 'configure', 'configuration bits', should show the values read from the chip.
