12.8.2.6 Mode of operation depending on PDI_datain
PDI supports following modes (other than the Slave mode):
• 8-bit monochrome (8-bit input data, each pixel info is coming in 1 clocks)
• 16-bit—RGB565 (16-bit input data, each pixel info is coming in 1 clocks)
• 18-bit—RGB666 (18-bit input data, each pixel info is coming in 1 clocks)
• 16-bit—RGB565 (8-bit input data, each pixel info is coming in 2 clocks)
• 16-bit—YCbCr422 (8-bit input data, info for 2 co-sited pixels coming in 4 clocks)
Data info extraction is given in Table 12-69.
