PRODUCTION DATA.
The deserializer has a PDB input pin to ENABLE or POWER DOWN the device. This pin can be controlled by the system to save power, disabling the deserializer when the display is not needed. An auto detect mode is also available. In this mode, the PDB pin is tied High and the deserializer will enter power down when the serial stream stops. When the serial stream starts up again, the deserializer will lock to the input stream and assert the LOCK pin and output valid data. In power-down mode, the Data and PCLK output states are determined by the OSS_SEL status.
NOTE
In power down, the optional Serial Bus Control Registers are RESET.
