Table 8. HDMI Control

ADDRESS BIT DEFAULT DESCRIPTION ACCESS
0Bh 7:6 2’b00 SLEW_CTL. Slew rate control.2’00 is fastest and 2’b11 is slowest
Writes ignored when I2C_EN/PIN = 0 		RWU
5 1’b0 HDMI_SEL: Contro; Writes ignored when I2C_EN/PIN = 0l
0 – HDMI (default)
1 – DVI		 RWU
4:3 2’b00 TX_TERM_CTL: Controls termination for HDMI TX
00 – No termination
01 – 150 to 300-Ω
10 – Reserved
11 – 75 to 150-Ω
Note: Reflects the value of the TX_TERM_CTL pin; Writes ignored when I2C_EN/PIN = 0 		RWU
2 1’b0 Reserved R
1 1’b0 TMDS_CLOCK_RATIO_STATUS: This field is updated from snoop of I2C write to slave address 0xA8 offset 0x20 bit 1 that occurred on the SDA_SRC/SCL_SRC interface. When bit 1 of address 0xA8 offset 0x20 is written to a 1’b1, then this field will be set to a 1’b1. When bit 1 of address 0xA8 offset 0x20 is written to a 1’b0, then this field will be set to a 1’b0. This field is reset to the default value whenever HPD_SNK is de-asserted for greater than 2 ms.
0 – TMDS clock is 1/10 of TMDS bit period (default)
1 – TMDS clock is 1/40 of TMDS bit period 		RWU
0 1’b0 DDC_TRAIN_SET: This field indicates the DDC training block function status. If disabled, the device can only work at the HDMI1.4b[2] or DVI mode
0 – DDC training enable (default)
1 – DDC training disable
Note: To force TMDS_CLOCK_RATIO_STATUS to 1, this register bit must be set to 1 which will force the 1/40 mode for HDMI2.0. 		RW
0Ch 7:5 3’b000 VSWING_DATA: Data output swing control
000 – Vsadj set
001 – Increase by 7%
010 – Increase by 14%
011 – Increase by 21%
100 – Decrease by 30%
101 – Decrease by 21%
110 – Decrease by 14%
111 – Decrease by 7%		 RW
4:2 3’b000 VSWING_CLK: Clock Output Swing Control
000 – Vsadj set
001 – Increase by 7%
010 – Increase by 14%
011 – Increase by 21%
100 – Decrease by 30%
101 – Decrease by 21%
110 – Decrease by 14%
111 – Decrease by 7%
Note: Default is set by DR, which means standard based swing values but this allows for the swing to be overridden by selecting one of these values		 RW
1:0 2’b00 HDMI_TWPST1. HDMI de-emphasis FIR post-cursor-1 signed tap weight.
00 – No de-emphasis
