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.

Use of the EMIF module (SDRAM controller) requires GPREG1[31] to be set

From UM 4.3.3 Control of Special Multiplexed Options

Any application that requires the EMIF functionality must set GPREG1[31]. This allows these 8 EMIF module outputs to be driven on to the assigned balls.

   systemREG1->GPREG1 |= 0x80000000;
