-- 01   Initial
-- 02   14 Mar 01   Verified through additional ATPG tools
--                  Changed BGA_49 to BGA_49_INTEGER. Added BGA_49_BALL
--                  Reversed order of DIN from (9 downto 0) -> (0 to 9)
--                  Corrected ID code
--                  Corrected RUNBIST
-- 03   21 Mar 01   Corrected ID
--                  Corrected cell ordering i.e. cell closest TDO = 0
-- 04   29 Mar 01   Corrected control cells
-- 05   29 Mar 01   Corrected disable value
-- 06   29 Apr 02   Corrected attribute ordering (RUNBIST_EXECUTION) & fixed bist register name
