Problem Title:
96 DATA BOOK: XC4000EX Program Data and Prom size (bits), p. 4-58


Problem Description:
7/96 and 9/96 DataBook
XC4000EX Program Data, p. 4-58, Table 23
Numbers in table are INCORRECT for Program Data and PROM Size (bits).


Solution 1:

To get the correct numbers, use the following formulas:
   Program Data = (Bits per Frame x Number of Frames) + 5 postamble bits
   PROM Size = Program Data + 40 (header) + 8
Note 1 will be corrected in the upcoming databook revision.


Correct program data and prom sizes are (in bits):

xc4028EX/XL    668,124	   668,172
xc4036EX/XL    832,480	   832,528
xc4044EX/XL  1,014,876	 1,014,924
xc4052XL     1,215,320	 1,215,368
