DWMBB/A Module Registers

Failing Address Register (XFADR)

The Failing Address Register logs address and length information associated

with a failing transaction. The DWMBB locks this register only if the

transaction fails. The error bits that lock this register and XFAER 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<15>

• Transaction Timeout (TTO), XBER<13>

• Internal Error, AESR<7>

Failing Length (FLN)

bits<31:30>

Name: Failing Length

Mnemonic: FLN

Type: RO, 0

FLN logs the value of XMI D<31:30> during the command/address

cycle of a failed XMI commander transaction. FLN loads on every

C/A cycle issued by the DWMBB. It locks only after all retries of the

transaction fail and unlocks when the error that caused the lock is

cleared.

bits<29:0>

Name: Failing Address

Mnemonic: None

Type: RO, 0

The Failing Address ﬁeld logs the value of XMI D<29:0> during the

command cycle of a failing transaction. Failing Address loads on every

C/A cycle issued by the DWMBB. It locks only after all retries of the

transaction fail and unlocks when the error that caused the lock is

cleared.
