If PDI is the background layer, no other layer can be a background layer for that particular frame. One and
only background layer is possible i.e. PDI Layer when PDI is enabled.
12.8.2.3 Features
The PDI supports the following:
• RGB565, RGB666, 8-bit monochrome format,YCbCr422 mode
• Max input frequency of 32 MHz in 8/16/18 normal mode input
• Max input frequency of 64 MHz in 8-bit muxed (Narrow) mode.
• External Synchronization using Hsync, Vsync, and Pdi_clk
• External Synchronization using Hsync, Vsync, DataEn and pdi_clk
• Internal synchronization using pdi_datain and pdi_clk is supported for RGB565 and YCbCr422
muxed mode only.
12.8.2.4 Normal and Narrow mode
In normal mode, PDI support maximum input frequency of 32 MHz. In narrow mode, PDI supports
maximum input frequency of 64 MHz.
