MSP430F5239

Other Parts Discussed in Thread: MSP430F5239

Hi Folk

Ok, I seem to have encountered another glitch:

Processor:  MSP430F5239

Package: RGC

CLK: 20Mhz

IDE: CCS

Programmer: FET430

Issue:

I am trying to initialise PORT 7 as GPIO's, now the problem is that if I start a debug session, and look in the "REGISTERS" I do not see PORT7. I only see Ports 1-6 available.

I looked in the MSP430F5239.h file and there is nothing on PORT7, however in the data sheet on page 86 is shows PORT 7 and a comment below says that it is not available in RGV (48 pin) devices. The PIN OUT for the 5239 device clearly shows that PORT 7 is available.

Have I missed something or is something missing in the .h file

Thanks in advance

    This solves the problem

    Hello Mark,

    Thanks for bringing this to our attention.  You are correct that PORT 7 register adderss is missing from the MSP430F5239.h header file.  I have filed a bug to have that updated.  In the meanwhile, I believe you should be able to update the header file to include PORT 7 base address.
