PRODUCTION DATA
As the programming interface can be intentionally deactivated using the EEPROM, an accidental disabling of the I2C blocks further access to the device. The serial interface can be forced using the fall-back mode. To enter this mode, the user leaves pin 4 and pin 23 floating while the supply voltage is applied to VDDREF. In this mode, pin 11 is preconfigured as an input and pin 20 is configured as an output.
