 Function:
    zl5011xIsrDisableFreeze

 Description:
   This function does the exact opposite of the IsrEnableFreeze function, it uses
   the same parameter structure (see below) as that function. Here
   the freeze mode is disabled if the bit is set.

   The top level mask contained in the ADM block is updated to cancel the
   ability of the relevant block or part-of-block to freeze the hardware.

 Inputs:
   zl5011xParams      Pointer to the structure for this device instance
   par               pointer to  parameter structure

 Structure Inputs:
   interruptBits - bits set to Disable the interrupt corresponding to the
                        ADM hardware freeze Enable register.

 Outputs:

 Returns:
    zlStatusE

 Function:

 Description:
   This function is used to get from the device the first interrupt

   it in an  intr message ready for sending to the DPR
   This is also a convenient function to tidy up any intrs not cleared by reading.

 Inputs:
