For direct access mode f9 operations, assertion of PE enables f9 algorithm-specified padding per the value
in the data size register. If this direct access mode operation includes the final message block, then PE must
be set in the KEU mode register as follows:

PE = 0: The KEU does not perform padding. For the KEU to perform the correct computation, the
last block of the message provided must be a complete 64-bit block, and the value written into the
KEU data size register must indicate a multiple of 64 bits.
PE = 1: The KEU pads the final 64 bits of the message as specified in the 3GPP f9 algorithm. The
communication direction (CD) bit (see
and ‘1’ is appended to the end of the message. The result is zero-padded to 64 bits.
For example, if the last block is xF81A_0000_0000_0000 (big endian) and data size contains 0x0F
(15 bits = 1 byte + 7 bits), the word (0xF81A = 1111_1000_0001_1010), the most-significant 15
bits (underlined) are padded left to right as
1111_1000_0001_101$_1000_0000_0000_0000_0000_0000_0000_0000_0000_0000_0000_000
0, where $ is the value of the CD bit in the mode register.

Clear Interrupts.
Setting this bit causes the KEU interrupt signals—DONE and ERROR—to be reset. It further resets the state
of the KEU interrupt status register.
