Outgoing Data Mode
In this mode the IC sends data to the IFD. The first bit becomes valid on I/O after the first falling edge
on CLK. After the last data bit an additional clock pulse is necessary in order to set I/O to high
impedance Z and to prepare the IC for a new command entry. During this mode any start and stop
condition is discarded.
Processing Mode
In this mode the IC processes internally. The IC has to be clocked continuously until I/O, which was
switched to level L after the first falling edge of CLK, is set to high impedance level Z. Any start and
stop condition is discarded during this mode.
Note: The RST line is low during the modes mentioned above. If RST is set to high during the CLK

low level any operation is aborted and I/O is switched to high impedance Z (Break).
