Problem Title:
XC3000/XC2000: Makebits-  CRC checking does not exist for configuration
in  2K and 3K devices



Problem Description:
Urgency: Standard

Keywords: CRC, bitstream, XC2000, XC3000

Description

Makebits:  Is there a makebits option to enable CRC
in the 2K and 3K devices?


Solution 1:

NCRC isn't part of the data frame in 2K and 3K devices.
The Data frame consists of the start bit (0), followed by
a 71-bit Data Field, ending with 3 stop bits.

For more details, refer to page 2-120 of the '94 Data Book.
