Sensor stays in this mode with SICI interface enabled. To return to normal interface, sensor reset is necessary
(can be done by power-down or sending the reset command 0x0001 to address 0x01:

Writing EEPROM with SICI

The following example in
0x006. In this example, it is assumed, that the sensor is connected in a bus mode configuration and has the
ID = 1. First the EEPROM page 0x006 is mapped to registers 0x60 to 0x67. Then these registers are read. After
that the content of the registers 0x60 and 0x67 can be changed. Care has to be taken that reserved bits and
bits which shall not be changed are written back without modification. Following that the EEPROM is burned.
Further details for bus mode programming can be found in

Ready DATA from register 0x67, corresponds to content
of EEPROM address 0x006E
Reset command, sensor restarts with default interface

Comment
Write command to address 0x77
unlocks registers
Write command to address 0x6C with DATA 0x4000
sensor will stay with SICI interface after power-on time
and not switch to preconfigured interface
SENT/SPC/PWM;
The first two commands have to be sent within the start-
up time of the sensor.
Write ID-WORD for ID=1 to address 0x7A;
only sensor with ID=1 is addressed; only necessary in
case of programming in a bus mode configuration
Write command to address 0x6C with DATA 0xC000
internal DSP is stopped
Maps EEPROM page 0x006 to registers 0x60 ... 0x67
(WRITE command to address 0x68)
Reads DATA from register 0x60,
corresponds to content of EEPROM address 0x0060

Ready DATA from register 0x67, corresponds to content
of EEPROM address 0x006E
Writes newDATA to register 0x60,
corresponds to intended new content of EEPROM
