CCS/TMS570LS3137: Missing HET registers

Part Number: TMS570LS3137
Other Parts Discussed in Thread: HALCOGEN

Tool/software: Code Composer Studio

Hello,

I miss all the HWA series of registers in my het_reg.h from Halcogen.

So, I tried to solve by simply appending the one of the missing (like HWAPINSEL) to the list by the modification of reg_het.h below at the struct hetBase; but, it does not figure among the registers during debug and the "watch" tab of CCS returns continuously "identifier not found". 

typedef volatile struct hetBase
{
    (all the registers from GCR to PINDIS)

    uint32   rsvd6; /**< 0x0098: Reserved                             */
    uint32 HWAPINSEL;/**< 0x009C: HWAG Pin select register            */

} hetBASE_t;

Where else should I apply modifications to locate also that register?

Thanks.

Regards.
