Xilinx Jtag Configuration source code, Support *.xsvf file

/*****************************************************************************
* file:         micro.c
* abstract:     This file contains the function, xsvfExecute(),
*               call for interpreting the XSVF commands.
* Usage:        Call xsvfExecute() to process XSVF data.
*               The XSVF data is retrieved by readByte() in ports.c
*               Remove the main function if you already have one.
* Options:      XSVF_SUPPORT_COMPRESSION
*                   This define supports the XC9500/XL compression scheme.
*                   This define adds support for XSDRINC and XSETSDRMASKS.
*               XSVF_SUPPORT_ERRORCODES
*                   This define causes the xsvfExecute function to return
*                   an error code for specific errors.  See error codes below.
*                   If this is not defined, the return value defaults to the
*                   legacy values for backward compatibility:
*                   1 = success;  0 = failure.
* Debugging:    DEBUG_MODE (Legacy name)
*               Define DEBUG_MODE to compile with debugging features.
*               Both micro.c and ports.c must be compiled with the DEBUG_MODE
*               defined to enable the standalone main implementation in
*               micro.c that reads XSVF from a file.
* History:      v2.00   - Original XSVF implementation.
*               v4.04   - Added delay at end of XSIR for XC18v00 support.
*                         Added new commands for CoolRunner support:
*                         XSTATE, XENDIR, XENDDR
*               v4.05   - Cleanup micro.c but leave ports.c intact.
*               v4.05.01- Added support for defining dynamic device targets.
*               v4.06   - Fix xsvfGotoTapState for retry transition.
*               v4.07   - Update example waitTime implementations for
*                         compatibility with Virtex-II.
*               v4.10   - Add new XSIR2 command that supports a 2-byte
*                         IR-length parameter for IR shifts > 255 bits.
*               v4.11   - No change.  Update version to match SVF2XSVF xlator.
*               v4.14   - Added XCOMMENT.
*               v5.00   - Improve XSTATE support.
*                         Added XWAIT.
*               v5.01   - make sure that TCK is low during RUNTEST wait for
*                         XC18V00/XCF00 support.  Only change is in PORTS.C
*                         waitTime() function for implementations that do NOT
*                         pulse TCK during the waitTime.
*               v5.01.03 - Fix trailer shift sequence in xsvfShift.

============================================================================*/

/*****************************************************************************
* Struct:       SXsvfInfo
* Description:  This structure contains all of the data used during the
*               execution of the XSVF.  Some data is persistent, predefined
*               information (e.g. lRunTestTime).  The bulk of this struct's
*               size is due to the lenVal structs (defined in lenval.h)
*               which contain buffers for the active shift data.  The MAX_LEN
*               #define in lenval.h defines the size of these buffers.
*               These buffers must be large enough to store the longest
*               shift data in your XSVF file.  For example:
*                   MAX_LEN >= ( longest_shift_data_in_bits / 8 )
*               Because the lenVal struct dominates the space usage of this
*               struct, the rough size of this struct is:
*                   sizeof( SXsvfInfo ) ~= MAX_LEN * 7 (number of lenVals)
*               xsvfInitialize() contains initialization code for the data
*               in this struct.
*               xsvfCleanup() contains cleanup code for the data in this
*               struct.
