Error Detection

Data Sheet

V 1.0, 2008-07

Error Detection

Different error cases can be detected by the On-Board Diagnostics (OBD) and reported

to the microcontroller in the status nibble (see Chapter 13).

7.1

Voltages Outside the Operating Range

The output signals an error condition if

VDD crosses the overvoltage threshold level.

7.2

EEPROM Error Correction

The parity method is able to correct a single bit in the EEPROM line. One other single bit

error in another EEPROM line can also be detected, but not corrected. In an

uncorrectable EEPROM failure, the open drain stage is disabled and kept in the off state

permanently (high ohmic/sensor defect).
