Field
31–12 Reserved, should be cleared.
11 DMA request level error. Indicates that the input and/or output DMA request level (SKMR[IDMAL] or SKMR[ODMAL])
DRL was set to an invalid request size. When the IDMA or ODMA bit is set, the request level must be set to a value of
1-32 words. Zero is considered an invalid request level.
0 No error
1 Invalid DMA request level
10 Key read error. An illegal attempt to read the key registers during processing has been detected.
KRE 0 No error
1 Key read error occurred
9 Key parity error. Indicates if a DES key parity error has occurred. Key parity checking can be disabled by setting the
KPE SKMR[DKP] bit (See
0 No error
1 Key parity error occurred
8 Early read.
ERE 0 No error
1 A context register was read from while the module was busy processing data.
7 Register modified during processing
RMDP 0 No error
1 A register was modified during processing
6 Key size error
KSE 0 No error
1 Illegal key size was written into the SKHA key size register
5 Data size error
