MSP430F248: Peripheral Register bit definitions

Bob Scott

Part Number: MSP430F248

Where are the peripheral register bits defined?  Can't seem to find it.

It used to be in the User's Guide I think but isn't now.

Regards

    when you include <msp430.h>, this in turns includes <msp430f248.h> because of compile time macros.

    You can look for msp430f248.h in your file system. (Ti puts a dozen copies in various places).

    For example, see C:\ti\ccsv7\ccs_base\msp430\include\msp430f248.h

    You can also click on any symbol in your source code, that is a Peripheral Register reference, then press Function F3 -- which brings up the msp430f248.h file.

    Hello Bob,

    Every peripheral has their registers defined in the family User Guide for the part it is on. The registers for a specific peripheral are defined and outlined at the end of the respective peripheral chapter. For example, the TimerB module has its register definitions in section 13.3 of the User Guide.

    This certainly does not tell me which bits are where in which register. The dot h file is fine but it does not define the register(s) - for example the flash control registers although there are many, many examples. When I'm writing in assembly I really do need register bit information and itss damn nice to have in c. It used to be provided. Where is it now???

    got it. I see JH says, "refer to the family User Guide," but that's a little non-specific.
    You want the document titled MSP430x2xx Family User's Guide (Rev. J)
    Which can be downloaded from TI at this URL: www.ti.com/.../slau144j.pdf

    Bob,

    To clarify, the family user guide for your part is located on its product page. this allows you to get the most up to date version.  MSP430F248

    Bob,

    Can you clarify which peripheral you are looking for register definitions? the last revision of this family's user guide was in 2013 (Rev J), and we haven't had a format change of the document since REV G.

    For example, below is an attached picture of a Timer A Register definition taken from the user guide. I assure you similar register definitions are provided for our other peripherals as well.
