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

Driver TxData Mode (Read Mode)

The Driver TxData–mode is a method to check the electrical interconnection between LCD

driver and baseband, to identify the driver and for VDD Intercfonnection electrical self testing.
