50 KPE Key parity error. The defined parity bits in the keys written to the key registers did not reflect odd parity
correctly. (Note that key register 2 and key register 3 are only checked for parity if the appropriate DEU mode
register bit indicates triple DES.
0 Key parity error enabled
1 Key parity error disabled
51 IE Internal error. An internal processing error was detected while performing encryption.
0 Internal error enabled
1 Internal error disabled
52 ERE Early read error. The DEU IV register was read while the DEU was performing encryption.
0 Early read error enabled
1 Early read error disabled
53 CE Context error. A DEU key register, the key size register, the data size register, the mode register, or IV register
was modified while DEU was performing encryption.
0 Context error enabled
1 Context error disabled
54 KSE Key size error. An inappropriate value (8 being appropriate for single DES, and 16 and 24 being appropriate
for Triple DES) was written to the DEU key size register
0 Key size error enabled
1 Key size error disabled
55 DSE Data size error (DSE): A value that is not a multiple of 64 bits was written to the DEU data size register.
0 Data size error enabled
1 Data size error disabled
56 ME Mode error. An illegal value was detected in the mode register.
0 Mode error enabled
1 Mode error disabled
57 AE Address error. An illegal read or write address was detected within the DEU address space.
0 Address error enabled
1 Address error disabled
58 OFE Output FIFO error. The shared symmetric output FIFO was detected non-empty upon write of DEU data size
register
0 Output FIFO non-empty error enabled
1 Output FIFO non-empty error disabled
