If the Interrupt Status Register is written from the core processor, 1s in the value written are
recorded in the Interrupt Status Register if the corresponding bit is unmasked in the Interrupt
Mask Register. All other bits are cleared. This register can also be cleared by setting the RI bit of
the AFEU Reset Control Register. The definition of each bit field in the AFEUISR is listed in
Table 26-56.

IE
12
0
Internal Error
Indicates whether an internal processing error
was detected while the AFEU was performing
encryption.
0
No internal error detected.
1
Internal error.
ERE

0
Early Read Error
Indicates whether the AFEU context memory or
control was read while the AFEU was
performing encryption.
0
No early read error detected.
1
Early read error.
CE

0
Context Error
If set, indicates that AESU key register, the Key
Size Register, Data Size Register, Mode
Register, or IV register was modified while the
AESU was processing.
0
No context error detected.
1
Context error.
KSE

0
Key Size Error
IF set, indicates that a value outside the range
1–16 bytes written to the AFEU Key Size
Register.
0
No key size error detected.
1
Key size error.
DSE

0
Data Size Error
If set, indicates that a value not a multiple of 8
bits was written to the AFEU Data Size
Register.
0
No data size error detected.
1
Data size error.
ME
7
0
Mode Error
If set, indicates that an illegal value was
detected in the Mode Register, likely caused by
writing to a reserved bit in that register.
0
Valid data.
1
Reserved or invalid mode selected.
AE

0
Address Error
If set, an illegal read or write address was
detected within the AFEU address space.
0
No address error detected.
1
Address error detected.

0
Output FIFO Error
If set, the AFEU output FIFO was detected
non-empty upon write of AFEU Data Size
Register.
0
No output FIFO error detected.
1
Output FIFO non-empty error.
IFE

0
Input FIFO Error
If set, the AFUE input FIFO was detected
non-empty upon generation of a done interrupt.
0
No input FIFO error detected.
1
Input FIFO non-empty error.
