ADDRESS 0-0A/0B/0C/0D: AUTHENTICATION SECRET
SET #3 (SE3A/B/C/D)
These address locations store the optional third set of
secrets to be used for hash calculation. Reading and writing
to this register can be disabled by setting the SLO[0] bit at
OTP ROM location 0-00[0].

TABLE 14. MASTER CONTROL REGISTER (MSCR)
TABLE 15. DEVICE STATUS REGISTER (STAT)
OTP ROM Write-in-Progress Interrupt Enable: When enabled, it allows the sEEW bit to flag an
interrupt whenever the sEEW bit is set by its interrupt event. The eEEW bit is fixed at ‘1’ when none
of the OTP ROM lock-out bits are set. When any or both of the lock-out bits are set, the eEEW bit
will become permanently ‘0’ after a reset.
Global Interrupt Enable: When enabled, it allows the sBER or sACC bit to flag an interrupt to the
host whenever any of the respective interrupt events occur.
(Default setting loaded from OTP ROM location 0-00[3])
Unused.
Auto Sleep Mode Enable: When set, the ISL9206A will automatically enter Sleep mode after about
1s of XSD bus inactivity. When cleared, the device can only enter Sleep mode on Opcode
command.
(Default setting loaded from OTP ROM location 0-00[2])
Soft Reset: When a ‘1’ is written, and all registers are reset to their default states, all bus counters
and timers are reset to their start-up conditions, and device configuration information is reloaded
from OTP ROM. After the reset sequence is completed, a ‘break’ pulse is sent to the host.
OTP ROM Write-in-Progress Flag: This bit is set when an attempt is made by the host to read from
or write to the ISL9206A while the ROM is still processing the previous write instruction.
XSD Bus Error Flag: This bit is set when one or more of the following occurs at the bus interface:
a) An invalid pulse width is received
b) Bus activity is detected before the device completes its power-up sequence
c) An invalid BYTES field in the instruction frame
d) Improper authentication sequence is detected
e) Reading secret information after the corresponding lock-out bits are set
Register Access Error Flag: This bit is set whenever an instruction frame attempts to access a
protected register as follows:
a) Writing to OTP ROM after the ISL9206A has been locked out (any or both of the lock-out bits
set)
b) Accessing the ISL9206A’s Test and Trim Registers when the device is not in test mode
Unused
Device Address Bit Setting:
Loaded from OTP ROM location 0-00[7:6] during power-up.
Secrets Lock-out Bits Setting:
Loaded from OTP ROM location 0-00[1:0] during power-up.
ISL9206A
Alternately, this memory space can be used to store
additional cell information which can be accessed by the
host. In this case, the SLO[0] bit should not be set.
