30 / 39 page TLE4998S Calibration Data Sheet 30 V 1.0, 2008-07 9.2 Programming Interface 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 • The bus-type connection of several sensors and separate programming via the OUT pin 9.3 Data Transfer Protocol The data transfer protocol is described in a separate document (User Programming Description), available on request. 9.4 Programming of Sensors with Common Supply Lines 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. Table 17 Programming Characteristics Parameter Symbol Limit Values Unit Notes min. max.
