/** \file   TwIf.c 
 *  \brief  The TWD bottom API towards the Txn-Queue. 
 *
 * The TwIf module is the lowest WLAN-specific layer and presents a common interface to all Xfer modules.
 * As such, it is responsible for the common functionalities related to device access, which includes:
 *    - transactions submission
 *    - interface power control
 *    - address translation (paging) when needed (depends on bus attributes).
 * The TwIf has no OS, platform or bus type dependencies.
 * 
 *  \see    TwIf.h, TxnQueue.c, TxnQueue.h
