//  1.00| 11 Sep 2003 | L.H. | Changes since previous version (v.58 Alpha) 
//      |             |      | As of Rev C silicon, DEVICEID is a 16-bit 
//      |             |      |    register  
//      |             |      | Commented out the DFT test registers.  These 
//      |             |      |    are not needed as of Rev C silicon.
