-/*****************************************************************************
- * 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.
- * v4.06 - 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.

- * Struct: SXsvfInfo
- * Description: This structure contains all of the data used during the

- * 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
