Hello,
Can you refer to section 7.6 in the DS90UB953-Q1 datasheet for information on pattern generation? The datasheet provides information on the pattern generation settings and also includes an example code.

Hello Palaniappan,
Thank you for your prompt Answer, I couldn’t find the details on how to change the video format on the datasheet.
On page 59, it give a table [Table 144. PGEN_CSI_DI (Address 0x03)] shows example of setting 0x03 register to display RGB888 format (by setting bits 5:0 to 0x24), but how to change the format to YUV422 format?

Hi Osama,

Please refer to the thread here: e2e.ti.com/.../696737

The thread contains some example code to change the format to YUV422.

Regards,
Jonny
