* 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().
