ADDRESS 0-00: DEFAULT CONFIGURATION (DCFG)
This address location stores the default configuration when
the ISL6296 is manufactured. Table 11 describes each bit in
detail. The legend for the TYPE column is given in Table 13.
ADDRESS 0-01: DEFAULT TRIM SETTING (DTRM)
This address location is writable only when the device is in
test mode. During normal operation, any data written to it will
be ignored. Table 12 describes the DTRM address in detail.
ADDRESS 0-02/03/04/05: AUTHENTICATION SECRET
SET #1 (SE1A/B/C/D)
These address locations store the first set of secrets to be
used for hash calculation. Reading and writing to this
register can be disabled by setting the SLO[1] bit at OTP
ROM location 0-00[1].
