Hi, E2E member
I would like to know the reading sequence of EDID in the External local EDID (EEPROM) mode.
My understanding is here.
1. Connect HDMI Source cable to HDMI port in DS90UH929-EVM.
2. Turn on the RX_5V from HDMI Source.
3. Turn on the External EEPROM on DDC line by RX_5V.
4. Pull-up to DDC line by RX_5V.
5. HPD pin goes to Hi from Low.
6. DS90UH929 acesses to Exteranl EEPROM and reads EDID data to internal SRAM in DS90UH929.
7. DS90UH929 provide the EDID to HDMI Source from internal SRAM.
8. HDMI Source provide the video signal of EDID.
Q1) Is this the correct procedure?
Q2) How long dose it take to Step8 from Step1?
Regards,
Nao
