Virtex SelectMAP configuration: Is D0 pin the MSB or LSB
Problem Description:
Urgency: Standard
General Description:
In application note Xapp138 and Xapp151, there are references stating that
D0 is MSB during configuration. Is D0 MSB or LSB during configuration?
Solution 1:
D0 is the MSB when the HEX file is used from the PROM File Formatter. The
default for the HEX file is to Swap Bits. When this option is deselected then
D0 becomes the LSB.
