  Function:
    I2C_RESULT I2CReceiverEnable ( I2C_MODULE id, BOOL enable )

  Summary:
    Routine to enable the module to receive data from the I2C bus

  Description:
    This routine enables the module to receive data from the I2C bus.

  Precondition:
    The module must have been configured appropriately and enabled, a transfer
    must have been previously started, and module must be the intended receiver
    of the next byte of data.

  Parameters:
    id      - Identifies the desired I2C module
    
    enable  - Determines if the receiver is to be enabled or disabled
              * If TRUE, enables the module to receive data on the I2C
              * If FALSE, disables the module from receiving data on the I2C

  Returns:
    None

  Example:
    <code>
    I2CReceiverEnable(I2C1, TRUE);
    </code>

  Remarks:
    This routine should be used by both master and slave receivers.
