ADDRESS BIT DEFAULT DESCRIPTION ACCESS
09h 7 1’b0 SWAP_EN: This field enables swapping the input main link lanes
0 – Disable (default)
1 – Enable
Note: field is loaded from SWAP/POL pin; Writes ignored when I2C_EN/PIN = 0		 RWU
6 1’b0 LANE_POLARITY: swaps the input data and clock lanes polarity.
0 – Disabled: No polarity swap
1 – Swaps the input data and clock lane polarity
Note: field is loaded from SWAP/POL pin; Writes ignored when I2C_EN/PIN = 0. This feature is only valid when in retimer mode. 		RWU
5:4 2'b00 Reserved R
3 1’b0 PD_EN
0 – Normal working (default)
1 – Forced power-down by I2C, lowest power state		 RW
2 1’b0 HPD_AUTO_PWRDWN_DISABLE
0 – Automatically enters power down mode based on HPD_SNK (default)
1 – Will not automatically enter power mode based upon HPD_SNK		 RW
1:0 2’b10 I2C_DR_CTL. I2C data rate supported for configuring device
00 – 5-kbps
01 – 10-kbps
10 – 100-kbps (default)
11 – 400-kbps (Note: HPD_AUTO_PWRDWN_DISABLE must be set before enabling 400 Kbps mode) 		RW
0Ah 7 1’b0 Application Mode Selection
0 – Source (default) - Set the adaptive EQ mid point to between 6.5-dB and 7.5-dB
1 – Sink - Sets the adaptive EQ starting point to between 12-dB and 13-dB		 RW
6 1’b0 HPDSNK_GATE_EN: This field sets the functional relationship between HPD_SNK and HPD_SRC.
0 – HPD_SNK passed through to the HPD_SRC (default)
1 – HPD_SNK will not pass through to the HPD_SRC.		 RW
5 1’b1 EQ_ADA_EN: this field enables the equalizer working state.
0 – Fixed EQ
1 – Adaptive EQ (default)
Writes are ignored when I2C_EN/PIN = 0		 RWU
4 1’b1 EQ_EN: this field enables the receiver equalizer.
0 – EQ disabled
1 – EQ enable (default) 		RW
3 1’b1 AUX_BRG_EN: this field enable the AUX bridge working.This is only valid for the 48-pin package.
0 – AUX bridge disable
1 – AUX bridge enable (default) 		RWU
2 1’b0 APPLY_RXTX_CHANGES , Self clearing write-only bit. Writing a 1 to this bit will apply new slew, tx_term, twpst1, eqen, eqadapten, swing, eqftc, eqlev settings to the clock and data lanes. Writes to the respective registers do not take immediate effect. This bit does not need to be written if I2C configuration occurs while OE or hpd_sink are low, I2C power down is active. W
1:0 2’b01 DEV_FUNC_MODE: This field selects the device working function mode.
00 – Redriver mode across full range 250 Mbps to 6-Gbps
01 - Automatic redriver to retimer crossover at 1.0 Gbps (default)
10 - Automatic retimer for HDMI2.0
11 - Retimer mode across full range 250 Mbps to 6-Gbps		 RW
When changing crossover point, need to toggle PD_EN or toggle external HPD_SNK.

Mode Selection Definition: This bit lets the receiver know where the device is located in a system for the purpose of centering the AEQ point. The SNx5DP159 is targeting the source application, so the default value is 0, which will center the EQ at 6.5 to 7.5-dB depending upon TMDS_CLOCK_RATIO_STATUS value, see Table 9. If the SNx5DP159 is in a dock or sink application, the value should be changed to a value of 1, which will center the EQ at 12 to 13-dB depending upon TMDS_CLOCK_RATIO_STATUS value.
