6.4.2 LP Mode

In this mode, the DPHY440 passes LP signals between DA[3:0]P/N and DB[3:0]P/N. The internal terminations for the HS receiver and HS transmitter are disabled when operating in this mode.

The MIPI DSI specification defines bidirectional communication between the host and peripheral. When a response is needed by the peripheral, the response is returned using LP signaling from DB0P/N to DA0P/N. The DPHY440 only supports this communication over lane 0 (DB0P/N to DA0P/N). The remaining lanes cannot be used for LP communications from peripheral to host (reverse direction).
