Please note a sideaffect of setting this bit is DCI function will be disabled. Therefore if DCI support is required, then this field must remain cleared. 0x0 = HPDIN is in default location 0x1 = HPDIN location is swapped (PIN 23 to PIN 32, or PIN 32 to PIN 23). 4 EQ_OVERRIDE R/W 0x0 Setting this field will allow software to use EQ settings from registers instead of value sampled from pins. 0x0 = EQ settings based on sampled state of EQ pins. 0x1 = EQ settings based on programmed value of each of the EQ registers. 3 HPDIN_OVERRIDE R/W 0x0 Overrides HPDIN pin state. 0x0 = HPD_IN based on HPD_IN pin. 0x1 = HPD_IN high. 2 FLIP_SEL R/W 0x0 This field controls the orientation. 0x0 = Normal Orientation 0x1 = Flip orientation. 1-0 CTLSEL R/W 0x1 Controls the DP and USB modes. 0x0 = Disabled. All RX and TX for USB3 and DisplayPort are disabled. 0x1 = USB3.1 only enabled. 0x2 = Four Lanes of DisplayPort enabled. 0x3 = USB3.1 and Two DisplayPort Lanes. 8.6.1.2 DCI_TXEQ_CTRL Register (Offset = 0xB) [reset = 0x6C] DCI_TXEQ_CTRL is shown in Table 14. Return to the Summary Table. This register controls the pre-shoot and de-emphasis levels for SSRX when limited redriver mode is enabled. Table 14. DCI_TXEQ_CTRL Register Field Descriptions Bit Field Type Reset Description 7-6 TX_PRESHOOT R/W 0x1 SSRX TX preshoot level (pre-cursor). 0x0 = 1.5dB 0x1 = 2dB 0x2 = 2.3dB 0x3 = 2.8dB 5 TX_PRESHOOT_EN R/W 0x1 SSRX TX preshoot (pre-cursor) enabled. Valid only when SSRX_LIMIT_ENABLE = 1. 0x0 = Disabled (0dB) 0x1 = Enabled |
