10.7.5.8
Following a done interrupt, the read-only KEU data out register holds the f9 message authentication code.
A 64-bit value is returned. This value may be truncated to 32 bits for some applications. Writing to this
location results in an address error reflected in the KEU interrupt status register.
10.7.5.9
The KEU end of message register, shown in
message block has been written to the input FIFO (in channel-driven access, this signaling is done
automatically). The KEU will not process the last block of data in its input FIFO until this register is
written. Once the end of message register is written, the KEU processes any remaining data in the input
FIFO and generates the done interrupt.
The value written to this register does not matter. A read of this register always returns a zero value.

KEU Data Out Register (f9 MAC) (KEUDOR)
KEU End of Message Register (KEUEMR)
According to the ETSI/SAGE 3GPP specification for f9 (version 1.2), only
32 bits of the final MAC are used. This corresponds to the lower 4 bytes of
the KEU data out register.
