Incorrect DMM GIO Pins Mapping

All operations to select pin as GIO, select pin direction etc. are buggy. All registers start by DMM SYNC (0), DMM CLK (1) and then follows DATA[0], but HalCoGen has different idea about pin mapping:

    dmmREG->PC1 =  1           /* DATA[0] */  /*!!! should be 1 << 2 !!!*/ 
                | (1 << 1)     /* DATA[1] */  /*!!! should be 1 << 3 !!!*/
                | (1 << 2)     /* DATA[2] */  /*!!! etc !!!*/
                | (1 << 3)     /* DATA[3] */
                | (1 << 4)     /* DATA[4] */
                | (1 << 5)     /* DATA[5] */
                | (1 << 6)     /* DATA[6] */
                | (0 << 7)     /* DATA[7] */
                | (0 << 8)     /* DATA[8] */
                | (0 << 9)     /* DATA[9] */
                | (0 << 10)    /* DATA[10] */
                | (1 << 11)    /* DATA[11] */
                | (0 << 12)    /* DATA[12] */
                | (1 << 13)    /* DATA[13] */
                | (1 << 14)    /* DATA[14] */
                | (0 << 15)    /* DATA[15] */
                | (0 << 16)    /* DMM SYNC */
                | (1 << 17)    /* DMM CLK */
                | (1 << 18);   /* DMM ENA */

PINMUX Does not Know Balls A3 (N2HET1[29]), J17 (N2HET1[31])

These pins do not have alternative functions, but corresponding PINMUX26 register bits has to be set to connect N2HET1 function signals to the pins.
