 * \brief HAL Function Prototypes
 *  The HAL4.0 API provides the user to have a interface for PN544(PN54x)/PN65N
 *  NFC device.The API is a non-blocking API, asynchronous API. This means that
 *  when ever an API function call results in waiting for a response from the
 *  NFC device, the API function will return immediately with status 'PENDING'
 *  and the actual result will be returned through specific callback functions
 *  on receiving the response from the NFC device
 *
 * \note This is the representative header file of the HAL 4.0. The release
 *       TAG or label is representing the release TAG (alias) of the entire
 *       library.A mechanism (see documentation \ref hal_release_label near
 *       the include guards of this file) is used to propagate the alias to
 *       the main documentation page.

*  This function is used to set parameters of various features of the Hal,
*  based on the CfgType parameter. Presently following configuration
*  types are supported :-
*  \n 1. NFC_RF_READER_CONFIG (optional)-> Configure parameters for Reader A
*     or Reader B based on the configuration passed
*  \n 2. NFC_P2P_CONFIG (optional)-> Congfigure P2P parameters like
*     'General bytes', 'PSL Request' etc.
*  \n 3. NFC_EMULATION_CONFIG -> Enable and configure the emulation mode
*     parameters for either NFC Target, SmartMX, UICC and
*  \n   Card Emulation from Host (A, B, F)
*  All the configuration modes can be called independent of each other. The
*  setting will typically take effect for the next cycle of the relevant
*  phase of discovery. For optional configuration internal defaults will be
*  used in case the configuration is not set.
*  \note Card emulation from Host and Card Emulation from UICC are mutually
*  exclusive modes, i.e: only one can be enabled at a time. Using
*  this function to enable one of the emulation modes implicitly disables the
*  the other. eg. Setting Type A (or Type B) Emulation from Host disables
*  card emulation from UICC and vice versa.
