Security Engine (SEC) 2.1
12.4.7.15 KEU Key Data Registers _3 and _4 (Integrity Key) (KEUKD n )
The KEU key data registers_3 & _4 together hold one 128-bit key that is used for F9 message
authentication. KEU key data register_3, (IK-high), holds the first 8 bytes (1-8). 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 a context error will occur.
If the F9 only mode is set, the integrity key data may be optionally written to KEU key data registers_1 &
_2. This eliminates the need for the host to offset from the base key address to write to KEU key data
registers_3 & _4 while using the KEU exclusively for the F9 integrity function.
Reading from either of these registers will result in an address error being reflected in the KEU interrupt
status register.
12.4.7.16 KEU FIFOs
The KEU fetches data 64 bits at a time from the KEU input FIFO. During F8 processing, the input data is
XORed with the generated keystream and the results are placed in the KEU output FIFO. During F9
