//! The TLV structure uses a tag or base address to identify segments of the

//! Descriptor, Interrupts, Info Block and Die Record. This function retrieves

//!
//! \param tag represents the tag for which the information needs to be
//!        retrieved.
//!        Valid values are:
//!        - \b TLV_TAG_RESERVED1
//!        - \b TLV_TAG_RESERVED2
//!        - \b TLV_TAG_CS
//!        - \b TLV_TAG_FLASHCTL

//!        instance. For example there may be multiple instances of timer
//!        calibration data present under a single Timer Cal tag. This variable
//!        specifies the instance for which information is to be retrieved (0,
//!        1, etc.). When only one instance exists; 0 is passed.

//!        retrieves the value of the TLV tag length. This value is pointed to

//!        function is called. If the specified tag is not found then the
//!        pointer is null 0.
//! \param data_address acts as a return through indirect reference. Once the
//!        function is called data_address points to the pointer that holds the
