/*****************************************************************************
* File:         micro.h
* Description:  This header file contains the function prototype to the
*               primary interface function for the XSVF player.
* Usage:        FIRST - PORTS.C
*               Customize the ports.c function implementations to establish
*               the correct protocol for communicating with your JTAG ports
*               (setPort() and readTDOBit()) and tune the waitTime() delay
*               function.  Also, establish access to the XSVF data source
*               in the readByte() function.
*               FINALLY - Call xsvfExecute().

* Function:     xsvfExecute
* Description:  Process, interpret, and apply the XSVF commands.
*               See port.c:readByte for source of XSVF data.
*               xsvfExecute supports dynamic device target assignment.
* Parameters:   iHir    - # bits to shift before instruction.
*                       = Sum of IR lengths following target device.
*               iTir    - # bits to shift after instruction.
*                       = Sum of IR lengths prior to target device.
*               iHdr    - # bits to shift before data.
*                       = # of devices (BYPASS reg.) following target device.
*               iTdr    - # bits to shift after data.
*                       = # of devices (BYPASS reg.) prior to target device.
*               iHdrFpga- # bits to shift before FPGA data.
*                       = special 32-bit alignment.
* Returns:      int - For error codes see above.
