(1)

PDATA(23:0) bus mapping is pixel format and source mode dependent. See later sections for details.

(2)

PDM_CVS_TE is optional for parallel interface operation. If unused, inputs should be grounded or pulled down to ground through an

external resistor (8 k

Ω or less).

(3)

Pixel clock capture edge is software programmable.

(4)

The parallel data mask signal input is optional for parallel interface operations. If unused, inputs should be grounded or pulled down to

ground through an external resistor (8 k

Ω or less).

(5)

Unused inputs should be grounded or pulled down to ground through an external resistor (8 k

Ω or less).

(6)

VSYNC, HSYNC, and DATAEN polarity is software programmable.

3DR

3D reference

•

For 3D applications: left or right 3D reference (left = 1, right = 0). To be provided by the

host when a 3D command is not provided. Must transition in the middle of each frame

(no closer than 1 ms to the active edge of VSYNC)

•

If a 3D application is not used, then this input should be pulled low through an external

resistor.
