Updated pinout to remove Vout reference on pin 40 08/060/08 2. Updated VDD_IO pin descriptions to show 1.05V to 3.3V operation 1. Fixed Pagination of Pin Descriptions 2. Changed reference to PCI3 Config Table in Pindes to match table name 8/8/2008 3. Added Byte 29 for Slew Rate control 1) 2) 3) 4) 5) 10/10/2008 6) 1) 4/28/2009 2) Page # 1, 3 2,3,17 Byte 11, bit 5 is now reserved. Byte 29, bits 7:6 default to 0.8X slew rate (‘10’) Removed reference to STOP drive mode in Power management table. Corrected REF slew rate control from Byte 29b3 to Byte 29b2. Clarified description of Byte 11, bits 2 and 3 to reflect CK505 ME clock selection table. Marked as Reserved all bits that are not in the 56-pin version of the device updated tables 2, 6 and 7 to clarify interaction of Config Modes with SRC1 Updated ordering revision to A Various 10, 11, 19, 20 This product is protected by United States Patent NO. 7,342,420 and other patents.
