“UG-214.pdf#page26” state for hardware power-down with internal E-EDID availability:
“The RESET pin must go low before or at the same time as the main system supply is removed.
The RESET pin must go low before or at the same time as the PWRDN1 goes low.”
When RESET pin is Low next register is set in his default state:
- EDID_A_ENABLE=EDID_B_ENABLE=0 ->“E-EDID for Port A,B disabled”, p.178
- EDID_A_ENABLE_CPU=EDID_B_ENABLE_CPU=0 -> “Disabled”
Internal E-EDID is disabled – how reading EDID from HDMI will work?
