8.4.1 Mode Select Configuration Settings (MODE_SEL[1:0])

Configuration of the device may be done through the MODE_SEL[1:0] input pins, or through the configuration register bits. A pullup resistor and a pulldown resistor of suggested values may be used to set the voltage ratio of the MODE_SEL[1:0] inputs. See Table 7 and Table 8. These values will be latched into the register location during power-up:

Table 6. MODE_SEL[1:0] Settings

MODE SETTING FUNCTION
EDID_SEL: Display ID Select 0 Look for remote EDID. If none found, use internal SRAM EDID. Can be overridden from register. Remote EDID address may be overridden from default 0xA0.
1 Use external local EDID.
AUX_I2S: AUX Audio Channel 0 HDMI audio.
1 HDMI + AUX audio channel.
EXT_CTL: External Controller Override 0 Internal HDMI control.
1 External HDMI control from I2C interface pins.
COAX: Cable Type 0 Enable FPD-Link III for twisted-pair cabling.
1 Enable FPD-Link III for coaxial cabling.
REM_EDID_LOAD: Remote EDID Load 0 Use internal SRAM EDID.
1 If available, remote EDID is copied into internal SRAM EDID.
