FUNCTION | DESCRIPTION |
|---|---|---|---|---|---|---|---|
| 0 | 0x00 | I2C Device ID | 7:1 | RW | Strap | DEVICE_ID | 7-bit address of Serializer. Defaults to address configured by the IDx strap pin. |
| 0 | RW | 0x00 | ID Setting | I2C ID setting.
0: Device I2C address is from IDx strap pin (default). 1: Device I2C address is from 0x00[7:1]. |
|||
| 1 | 0x01 | Reset
A software I2C reset command issued by writing to register 0x01 is supported only when operating I2C in the 3.3V mode. |
7:5 | 0x00 | Reserved. | ||
| 4 | RW | HDMI Reset | HDMI Digital Reset.
Resets the HDMI digital block. This bit is self-clearing. 0: Normal operation. 1: Reset. |
||||
| 3:2 | Reserved. | ||||||
| 1 | RW | Digital RESET1 | Reset the entire digital block including registers. This bit is self-clearing.
0: Normal operation (default). 1: Reset. Following the setting of this bit, the software should also set bit 0x4F[1] (BRIDGE_CTL register). This will restore register values that are initially loaded from Non-Volatile Memory to their default state. |
||||
| 0 | RW | Digital RESET0 | Reset the entire digital block except registers. This bit is self-clearing.
0: Normal operation (default). 1: Reset. Registers which are loaded by pin strap will be restored to their original strap value when this bit is set. These registers show 'Strap' as their default value in this table. Registers 0x00, 0x13, 0x15, 0x18, 0x19, 0x1A, 0x48-0x55, 0x58, 0x5B, 0xC0, 0xC2, 0xC3, 0xC6, 0xC8, 0xCE and 0xD0 are also restored to their default value when this bit is set. |
||||
| 3 | 0x03 | General Configuration | 7 | RW | 0xD2 | Back channel CRC Checker Enable | Enable/disable back channel CRC Checker.
0: Disable. 1: Enable (default). |
| 6 | Reserved. | ||||||
| 5 | RW | I2C Remote Write Auto Acknowledge
Port0/Port1 |
Automatically acknowledge I2C remote writes. When enabled, I2C writes to the Deserializer (or any remote I2C Slave, if I2C PASS ALL is enabled) are immediately acknowledged without waiting for the Deserializer to acknowledge the write. This allows higher throughput on the I2C bus. Note: this mode will prevent any NACK from a remote device from reaching the I2C master.
0: Disable (default). 1: Enable. If PORT1_SEL is set, this register controls Port1 operation. |
||||
| 4 | RW | Filter Enable | HS, VS, DE two-clock filter. When enabled, pulses less than two full TMDS clock cycles on the DE, HS, and VS inputs will be rejected.
0: Filtering disable. 1: Filtering enable (default). |
||||
| 3 | RW | I2C Pass-through
Port0/Port1 |
I2C pass-through mode. Read/Write transactions matching any entry in the Slave Alias registers will be passed through to the remote Deserializer.

||||
| 2 | Reserved. | ||||||

| 4:3 | RW | SDA Output Delay | Configures output delay on the SDA output. Setting this value will increase output delay in units of 40ns.
Nominal output delay values for SCL to SDA are: 00: 240ns (default). 01: 280ns. 10: 320ns. 11: 360ns. |
||||
| 2 | RW | Local Write Disable | Disable remote writes to local registers. Setting this bit to 1 will prevent remote writes to local device registers from across the control channel. This prevents writes to the Serializer registers from an I2C master attached to the Deserializer. Setting this bit does not affect remote access to I2C slaves at the Serializer.
0: Enable (default). 1: Disable. |
||||
| 1 | RW | I2C Bus Timer Speedup | Speed up I2C bus Watchdog Timer.
0: Watchdog Timer expires after approximately 1s (default). 1: Watchdog Timer expires after approximately 50µs. |
||||
| 0 | RW | I2C Bus Timer Disable | Disable I2C bus Watchdog Timer. The I2C Watchdog Timer may be used to detect when the I2C bus is free or hung up following an invalid termination of a transaction. If SDA is high and no signaling occurs for approximately 1s, the I2C bus will be assumed to be free. If SDA is low and no signaling occurs, the device will attempt to clear the bus by driving 9 clocks on SCL.
0: Enable (default). 1: Disable. |
||||
| 6 | 0x06 | DES ID | 7:1 | RW | 0x00 | DES Device ID
Port0/Port1 |

| 7 | 0x07 | Slave ID[0] | 7:1 | RW | 0x00 | Slave ID 0
Port0/Port1 |
7-bit I2C address of the remote Slave 0 attached to the remote Deserializer.

A value of 0 in this field disables access to the remote Slave 0.
If PORT1_SEL is set, this register is with reference to Port1. |

A write to this register will enable a frequency counter to count the number of pixel clock during a specified time interval. The time interval is equal to the value written multiplied by the oscillator clock period (nominally 40ns). A read of the register returns the number of pixel clock edges seen during the enabled interval. The frequency counter will freeze at 0xff if it reaches the maximum value. The frequency counter will provide a rough estimate of the pixel clock period. If the pixel clock frequency is known, the frequency counter may be used to determine the actual oscillator clock frequency. |
