PRODUCTION DATA.
| 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 01 – 2-dB de-emphasis 10 – Reserved 11 – Reserved |
