Error Registers

14.3.3.1

EMASK: Error Mask

This register masks errors in the FERR and NERR registers as well as disabling some

types of error detection. A ‘0’ in any field enables that error. A ‘1’ in any field masks

(disables) that error. Multiple bits can be set in this register. An enabled error sets

error status, updates error logs, and generates link signals. A masked error does not

affect error status, error logs, or link signals.

14.3.3.2

FERR: First Error

This register contains bits specifying which errors occurred first as related to the FBD

channel.

WBUFOVFL: Write Buffer overflow

- Implementation Specific - only supported for debug

6RWCST

WPLDERR: Wrong Number of Write Payloads (Buffer Underflow)

- Implementation Specific - only supported for debug

5RWCST

INJERR: Error Injection has sourced an injected error bit in the status

return field (optional)

4RWCST

INJALERT: Error Injection has sourced an injected alert error (optional)

3RWCST

FEWEDGES: tClk Training Violation (no sync cmd for2x SYNCTRAININT -

typically 84 frames)

Logs in RECFBD registers. Sends Alerts NB. Triggers auto self refresh SM.

2RWCST

OVERTEMP: Temp > TEMPHI and temp enabled

Fatal. AMB shuts down.

1RWCST

UNIMPLCFG: Unimplemented Configuration Address

Correctable. Logs in RECCFG* registers. AMB drops the command.
