AER control bitfield masks

Hi

In the AER 17.0.0.0 API documentation, bits 11 and 12 in control bitfield 1 are defined as:

        11         1       Keep clipper during double talk
                   0       Remove clipper completely during double talk        
        12                 RESERVED  

However the corresponding masks are defined as:

#define aer_CTL1_BIT_11_RESERVED 0x0800 /**< reserved */
#define aer_CTL1_RESET_PARAMS 0x1000 /**< reset config. params */

The mask seems to contradict the API, what enables are assigned to these bits?

Thanks,

Simon
