SN65DSI86: What is the required range of video format parameters?

Part Number: SN65DSI86

Hi TI,

What is the required range of video format parameters?(HPW/HBP/HFP、VPW/VBP/VFP)

1. I see from the datasheet that these registers are 8 bits, are they support up to 255?

2. What is the minimum support?

    Hello,

    HSYNC pulse width can be in the range of 0 <= HPW < 32767 pixel clocks, as the HPW is defined as a 15bit value. HBP and HFP can be in the range of 0 <= HBP, HFP < 255 pixel clocks.

    VSYNC pulse width can be in the range of 1 <= VPW < 32767 lines. VBP and VFP can be in the range of 1 <= VBP, VFP < 255 lines. 

    These parameters are found in the eDP panel EDID.

    Best, Allison
