/*= Module Overview *********************************************************
<verbatim>

Overview
The Advanced Qam Out Of Band (AOB) Downstream receiver is responsible for taking an
Out-of-Band RF signal (70-130 MHz), down converting into IF signal. This IF
signal is then digitalized, demodulated and error corrected. This error
corrected data stream can be then routed to Davic MAC.


Design
  The design for BAOB PI API is broken into three parts.

o Part 1 (open/close/configuration):

    These APIs are used for opening and closing BAOB device.
    When a device is opened, the device can be configured.

o Part 2 (acquire/get/set):

    These APIs are used for getting and setting runtime attributes of BAOB.
    Along with get and set APIs, an acquire API is also provided.  The acquire
    API is used to acquire (lock) OutOfBand Downstream signal.

o Part 3 (process):

    This API is used to process notification.

Usage
The usage of BAOB involves the following:

   * Configure/Open of BQOB

      * Configure BAOB device for the target system
      * Open BAOB device

   * Program/Acquire device

      * Try to acquire OutOfBand Downstream signal
      * Check status of acquisition
      * Wait for Lock/Unlock ntotification sent from 325X
         * Process Lock/Unlock Notification


Interrupt Requirements
No interrrupt processing is done by this module.


Sample Code:
//
// NOTE: The following sample code does not do any error checking.
//
// In this example, the target H/W board is configured for an
// Out-of-Band Downstream DVS 178 application, with a Crystal Frequency of 24.00 MHz
//

    // Configure the Crystal Frequency of H/W board.

                                      // true: legacy OOB needs FEC
    aobDevSettings.hRpc = hRpc;
    BAOB_Open( &aobDev, hChip3128, hReg3128, &aobDevSettings );


    // Now startup the RPC Notificiation Background thread/task . . .

    // Install callback for state change event, where last parameter
    // is for general use.
