Represents the length used in the AES operation for the packet to
be transmitted. It has a different meaning for each security mode
as follows.
Security mode: CTR – It represents the number of bytes between
length byte and the data to be encoded or decoded in FIFO.
Security mode: CBC-MAC – It represents the number of bytes
between length byte and the data to be authenticated.
Security mode: CCM – It represents the length of the data which is
used not in encoding or decoding but in authentication.
Reserved
Represents the length used in the AES operation for the received
packet. It has a different meaning for each security mode as
follows.
Security mode: CTR – It represents the number of bytes between
length byte and the data to be encoded or decoded of data in FIFO.
Security mode: CBC-MAC – It represents the number of bytes
between length byte and the data to be authenticated.
Security mode: CCM – It represents the length of the data which is
used not in encoding or decoding but in authentication.
Selects the KEY value for Standalone SAES operation. When this
field is ‘1’, KEY1 is selected and when ‘0’, KEY0 is selected.
Selects the KEY value for AES operation during packet
transmission. When this field is ‘1’, KEY1 is selected and when
‘0’, KEY0 is selected.
Selects the KEY value for AES operation during packet reception.
When this field is ‘1’, KEY1 is selected and when ‘0’, KEY0 is
selected.
In CBC-MAC operation, it represents the data length used in the
authentication field as byte unit.
