The following extract from the Virtex 4 RIO user guide states:
*/Serialization/**/As in Virtex-II Pro X devices, Virtex-4 also serializes and sends the least significant byte first. This is opposite of the format Virtex-II Pro devices used in sending the most significant byte first./*
What does this really mean?
Are the v2pro and v4 MGT's incompatible because of this?
Will it work if the bit order is reversed before sending or after recieving?
