associated with a failed XMI commander transaction. The DWMBB locks
XFAER only if the transaction fails. The error bits that lock this register and
XFADR follow:
• Write Data NO ACK (WDNAK), XBER<20>
• No Read Response (NRR), XBER<18>
• Read Sequence Error (RSE), XBER<17>
• Command NO ACK (CNAK), XBER<16>
• Transaction Timeout (TTO), XBER<13>
• Internal Error, AESR<7>
