4.1.1.2 Data/command transfer pause
It is possible while transferring Frame Memory Data, Commands or Command Parameters
to insert a pause in the data transmission (!CS Line HIGH after 8 Bits Received). When !CS
is forced high after a whole byte received, the received byte is processed. Then STE2007 is
forced in a wait state ready to restart processing incoming data from the point where the
communication has been paused
If a new command identifier is transferred after a pause condition the previous
communication session is definitively closed.
Four are the possible conditions:
– Command-Pause-Command
– Command-Pause-Parameter
– Parameter-Pause-Command
– Parameter-Pause-Parameter
