Bit Field Type Reset Description
7:6 Reserved R 00 Reserved.
5 SWAP_HPDIN R/W 0 0 – HPDIN is in default location (Default)
1 – HPDIN location is swapped (PIN 23 to PIN 32, or PIN 32 to PIN 23).
4 EQ_OVERRIDE R/W 0 Setting of this field will allow software to use EQ settings from registers instead of value sample from pins.
0 – EQ settings based on sampled state of the EQ pins (DPEQ[1:0]).
1 – EQ settings based on programmed value of each of the EQ registers
3 HPDIN_OVRRIDE R/W 0 0 – HPD based on state of HPDIN pin (Default)
1 – HPD high.
2 Reserved R/W 0 Reserved.
1:0 CTLSEL[1:0] R/W 01 Upon power-on, software must write 2'b10 to enable DisplayPort functionality. If DisplayPort functionality is not required, then software must write 2'b00 to disable DisplayPort.
00 - Shutdown. DP disabled and lowest power state.
01 - DP disabled but not in lowest power state.
10 - DP enabled
11 - Reserved.
