Header files with register bit field breakdowns?

Other Parts Discussed in Thread: TMS320F2812, HALCOGEN, TMS570LS3137, RM48L952

Does TI provide a package of header files similar to the TMS320F2812 C281x C/C++ Header Files and Peripheral Examples (including F281x). I am looking for a struct bit field breakdown for all of the registers of the TMS570LS3137 and 20216. I know that HalCoGen will provide a high level version of this.

For example, HalCoGen provides the following for the CAN peripheral CTL registers:

uint32 CTL;          /**< 0x0000: Control Register                       */

I would like something like the following:

union
{
    volatile uint32 R;
    struct {
        uint32 rsvd1:6;
        uint32 WUBA:1;
        uint32 PDR:1;
        uint32 rsvd2:3;
        uint32 DE3:1;
        uint32 DE2:1;
        uint32 DE1:1;
        uint32 IE1:1;
        volatile uint32 InitDbg:1;
        uint32 SWR:1;
        uint32 rsvd3:1;
        uint32 PMD:4;
        uint32 ABO:1;
        uint32 IDS:1;
        uint32 Test:1;
        uint32 CCE:1;
        uint32 DAR:1;
        uint32 rsvd4:1;
        uint32 EIE:1;
        uint32 SIE:1;
        uint32 IE0:1;
        uint32 Init:1;
    }
    B;
}CTL; /**< 0x0000: Control Register                       */

    Jeremy,

    HALCoGen is our primary tool to provide headers and drivers. I don't believe we have headers with bit fields, but let me check and get back to you.

    Hi Jeremy,

    HALCoGen headers does not support bit definitions to adhere to MISRA-C-2004. Drivers are written in a way to address the complete registers at 32bit boundary, user software / Driver will do bit manipulation where ever necessary.

    Hi Prathap,

    Is there any way to have HALCoGen create header files with bitfields (I do not require MISRA compliant header files)?  I find it rather shocking that TI expects the user to create the bitfields of hardware registers themselves.  I have been working with microcontrollers and embedded processors/software for over 13 years and have never once had to create bit definitions for the hardware registers for any parts I have used (even 8 bit micros with only 256 bytes of banked RAM) - the manufacturer/compiler provider has always supplied these in a header file in one form or another.  I have used micros from Atmel, Microchip, Freescale/Motorola, and Xilinx.  Please tell me TI provides these bit definitions so I don't have to spend hrs creating them from staring at the user manual.

    I really don't even need them to be generated by Halcogen.  If there exists a set of header files that provide the register and bit field definitions for a RM48L952, that would work for me.

    Thank you,

    Matt
