C:
#define Timer0              0x100
#define Timer1              0x108
#define Timer2              0x110
#define Timer3              0x118
#define Timer4              0x120
#define Timer5              0x128
#define Timer6              0x130
#define Timer7              0x138

uint16_t TmrAdd[][1] =
{
    Timer0,
    Timer1,
    Timer2,
    Timer3,
    Timer4,
    Timer5,
    Timer6,
    Timer7
};


static uint8_t TmrCount(void)
{
    uint8_t TCount = 0;
    uint8_t Tmr = 0;
    
    do
    {
        uint16_t bAdd = TmrAdd[TCount];
        Tmr = DATAEE_ReadByte(bAdd);
        if (Tmr != NoData)                      //NoData = 0xFF
        {
            TCount++;
        }
    }while (Tmr != NoData || TCount > 8);
    return TCount;
}

I am using this code to access EEPROM, using a 2D array for the EEPROM address.

C:
uint16_t bAdd = TmrAdd[TCount];

when I run the code and the above line bAdd ends up with the address of the array element and not the contents of the element.
How do I correct this?
 
You are addressing the 2D array by only one parameter. The result is a pointer to the start of the second parameter data.

You only need a single dimension for the list of addresses; just remove the second dimension in the definition.

Or address the array as TmrAdd[TCount][0];
