Later, to avoid additional power consumption in the output stage of the device, the
internal driver is deactivated as soon as the first clock pulse of a frame is detected, and
put on again after completion of the transmission. This is illustrated in
Figure 6
In case of a wrong command or data frame, the interface is immediately locked and the
device falls back to its normal application mode. As long as the device is in the interface
mode, selected test modes stay activated, too. Special transmission modes based on
these frames, used for programming of the EEPROM, will be explained in the EEPROM
programming section.
The read access to the device is triggered by clock pulses on the supply line as shown
in figure

As already described, the data transmission is performed by command frames. These
command frames are supported by following data frames, if required. A general
command frame is shown in
