Start Encryption (41H)
Start Decryption (40H)
Start (C0H)
The three “Start” commands begin normal data ciphering by
setting the Start/Stop bit (S7) in the Status Register to “1.”
The Start Encryption and Start Decryption commands
specify
the
ciphering
direction
by
forcing
the
Encrypt/Decrypt bit (M4) in the Mode Register to “1” or “0”,
respectively. Whereas Start uses the current state of the Mode
Register Encrypt/Decrypt bit, as specied in a previous
Mode Register load. When any Start command has been
entered, the port status ag (MFLG or SFLG) associated
with the Input Register will become active (LOW),
indicating that data may be written to the Input Register to
begin ciphering.
In Direct Control Mode, the Start command is issued by
raising the level of the AUX5-S/S input. If AUX6-E/D is high
when AUX5-S/S goes HIGH, the command is Start
Encryption; if AUX6-E/D is low, it is Start Decryption.
Stop (E0H)
The Stop command sets the Start/Stop bit (S7) in the Status
Register to “0.” This causes the input ag (
or
)
to become inactive and inhibits the loading of any further
data. Any ciphering in progress (Busy bit (S5) is “1” or
AUX2-
is active) will be completed and any data in the
Output Register will remain accessible (except in CFB
Mode). In either CFB Mode, the last byte of data must be
read out before issuing the Stop command.
In Direct Control Mode, the Stop command is implied when
the signal level on the AUX5-S/S input goes from HIGH to
LOW.
Software Reset (00H)
This command is similar to a hardware reset (CA95C68:
and
low, CA95C18:
and
low) in that
it forces the DCP back to its default conguration, and all the
processing ags go inactive. The default conguration for
the Mode Register is: Electronic Code Book cipher type and
dual port conguration with Master Port clear, Slave Port
encrypted.
