Problem Title:
DATABOOK 1996 Edition: Ambiguity regarding PG299 pins E5, E16, T5 and
T16



Problem Description:
The 1996 Xilinx databook is missing entries for the following PG299
package pins:

  E5, E16, T5, and T16.

In the May 1996 datasheet that was released prior to this,
they were missing from one table:

   "Technical data, XC4000 Series FPGA", Page 4-127.

In the same May 1996 datasheet, page 4-171,

  T5 and E16 are listed as GND, and
  T16 and E5 are listed as VCC.



Solution 1:

The information in the second table is correct:

- T5 and E16 are grouped with 16 other pins as Vss.
- T16 and E5 are grouped with 16 other pins as Vcc.
