10.7.5.14 KEU Key Data Registers_1 and _2 (Confidentiality Key) (KEUKD n )
The first two KEU key data registers, shown in
key that is used for f8 encryption/decryption. The KEU key data register_1, (CK-high), holds the first 8
bytes (1–8). The KEU key data register_2, (CK-low), holds the second 8 bytes (9–16). The KEU key data
registers must be written before message processing begins and cannot be written while the block is
processing data, or else, a context error occurs. Reading from either of these registers causes an address
error, which is reflected in the KEU interrupt status register.
10.7.5.15 KEU Key Data Registers _3 and _4 (Integrity Key) (KEUKD n )
The third and fourth KEU key data registers, shown in
128-bit key that is used for f9 message authentication. The KEU key data register_3, (IK-high), holds the
first 8 bytes (1–8). The KEU key data register_4, (IK-low), holds the second 8 bytes (9–16). The KEU key
data registers must be written before message processing begins and cannot be written while the block is
processing data, or else, a context error occurs.
If f9 only mode is set in the KEU mode register, the integrity key data may be optionally written to the
KEU key data registers_1 and KEU key data registers_2. This eliminates the need for the host to offset

For descriptor operation, if the entire context is unloaded for later reuse, the
context data size must be 72 bytes, and the output consists of KEU IV_1,
KEU ICV_In, KEU IV_2, and six KEU context data registers. For
operations performing processing of partial messages, if the context is
unloaded, the PE bit in the KEU mode register must not be set. Also, for
partial message processing, if the context is reloaded, the INT bit in the
KEU mode register must not be set.
