MSP430F5659: Questions regarding erasing code i Bank 0

I have two questions regarding MSP430f5659 and erasing code flash in Bank 0.

For me it seems that Bank 0 is split in two areas with the INTVEC (0xFF80-0xFFFF) in the middle.

1) Can I use “bank erase” without destroying the INTVEC area?

2) If I use “segment erase” in Bank 0, do I have to take special precaution in the segment where INTVEC is situated?

Thanks

Hi Ragnar,

Please view my responses below:

1.) Using bank erase on Bank 0 will erase the interrupt vectors as they are located in Bank 0. This is shown by section 1.11, page 72, of the MSP430x5xx and MSP430x6xx Family Users Guide

2.) As long as you are outside to the range the interrupt vectors are specified, you should be able to use segment erase without issues. Take a look at section 7.2, page 344 of the MSP430x5xx and MSP430x5xx Family User's Guide for more information.

Best,

-Chris

Hi Chris
I hoped the answer was "No problem, the INTVEC will survive", but now I know and can take necessary precaution.
