FC Config
1: Disable loading of this register from the forward
channel, keeping locally written values intact
0: Allow forward channel loading of this register
Pass RGB
Setting this bit causes RGB data to be sent
independent of DE. This allows operation in systems
which may not use DE to frame video data or send
other data when DE is deasserted. Note that setting
this bit blocks packetized audio. This bit does not need
to be set in DS90UB925 or in Backward Compatibility
mode.
1: Pass RGB independent of DE
0: Normal operation
Note: this bit is automatically loaded from the remote
serializer unless bit 7 of this register is set.
DE Polarity
This bit indicates the polarity of the DE (Data Enable)
signal.
1: DE is inverted (active low, idle high)
0: DE is positive (active high, idle low)
Note: this bit is automatically loaded from the remote
serializer unless bit 7 of this register is set.
I2S_Gen
This bit controls whether the Receiver outputs
packetized Auxiliary/Audio data on the RGB video
output pins.
1: Don't output packetized audio data on RGB video
output pins
0: Output packetized audio on RGB video output pins.
Note: this bit is automatically loaded from the remote
serializer unless bit 7 of this register is set.
I2S
Channel B
Enable
Override
1: Set I2S Channel B Enable from reg_22[0]
0: Set I2S Channel B Enable from MODE_SEL pin
Note: this bit is automatically loaded from the remote
serializer unless bit 7 of this register is set.
18-bit Video 1: Select 18-bit video mode
Select
0: Select 24-bit video mode
Note: this bit is automatically loaded from the remote
serializer unless bit 7 of this register is set.
I2S
Transport
Select
1: Enable I2S Data Forward Channel Frame Transport
0: Enable I2S Data Island Transport
Note: this bit is automatically loaded from the remote
serializer unless bit 7 of this register is set.
I2S
Channel B
Enable
I2S Channel B Enable
1: Enable I2S Channel B on B1 output
0: I2S Channel B disabled
Note: this bit is automatically loaded from the remote
serializer unless bit 7 of this register is set.
