9.2
The VDD pin and the OUT pin are used as a two-wire interface to transmit the EEPROM
data to and from the sensor.
This allows:
• Communication with high data reliability, parity protected
• The bus-type connection of several sensors and separate programming via the OUT
9.3
The data transfer protocol is described in a separate document (User Programming
Description), available on request.
9.4
In many automotive applications, two sensors are used to measure the same parameter.
This redundancy makes it possible to continue operation in an emergency mode. If both
sensors use the same power supply lines, they can be programmed together in parallel.
