Description
16
MSACP
Memory Scrubbing write back Redundant Address decode error. This bit indicates that an address-
control parity error occurred during memory scrubbing write back. This bit must be cleared by writing a 1
to it before any new error can be generated.
0
An address control parity error did not occur during memory scrubbing write back.
1
An address control parity error occurred during memory scrubbing write back.
15
CPEOI
Command Parity Error on Idle. This bit indicates an error occurred for an idle command with parity error.
This bit must be cleared by writing a 1 to it before any new error can be generated.
0
An error did not occur.
1
An error occurred.
14
Reserved
0
Reads return 0. Writes have no effect.
13
MIE
Memory Initialization Error. This bit indicated an error occurred for an access to a bank under memory
initialization. Access to a bank under memory initialization is not allowed. It will result in a false double
bit error. This bit must be cleared by writing a 1 to it before any new error can be generated.
0
An error did not occur.
1
An error occurred.
12
MMDE
Merged MUX Diagnostic Error. This bit indicates a error was detected on the compare logic of the mux
logic used for data merging of a read modify write operation during diagnostic test. This bit must be
cleared by writing a 1 to it before any new error can be generated.
0
An error did not occur.
1
An error occurred.
11
WEMDE
Write ECC Malfunction Diagnostic Error. This bit indicated an error was detected on the compare logic
of the write ECC malfunction during diagnostic test. This bit must be cleared by writing a 1 to it before
any new error can be generated.
0
An error did not occur.
1
An error occurred.
10
REMDE
Read ECC Malfunction Diagnostic Error. This bit indicated an error was detected on the compare logic
of the read ECC malfunction during diagnostic test. This bit must be cleared by writing a 1 to it before
any new error can be generated.
0
An error did not occur.
1
An error occurred.
9
MME
Merged Mux Error. This bit indicates an error was detected on the mux logic that is used to merge the
corrected read and write data for a read modify write operation. This bit must be cleared by writing a 1
to it before any new error can be generated.
0
An error did not occur.
1
An error occurred.
8
PACE
Address and/or Control bus Parity Error. This bit must cleared by writing a 1 to it before any new error
can be generated.
0
An error did not occur.
1
An error occurred.
7
RMWDE
Read-Modify-Write Double Bit Error. This bit indicates that an ECC uncorrectable (double bit) error was
detected during read access of the read modify write operation. This bit must be cleared by writing a 1
to it before any new error can be generated.
0
An error did not occur.
1
An error occurred.
6
Reserved
0
Reads return 0. Writes have no effect.
5
CPUWDE
CPU Write Double-bit Error. This bit indicates that an ECC uncorrectable (double bit) error was detected
during write access. This bit must be cleared by writing a 1 to it before any new error can be generated.
0
An error did not occur.
1
An error occurred.
