Page	Addr (hex)	Register Name	Bit(s)	Field	Type	Default	Description
Share	0x00	I2C Device ID	7:1	DEVICE ID	(R/W)/S	0x3D	7-bit I2C ID of deserializer Defaults to address configured by IDX strap pin. This field always indicates the current value of the I2C ID. When bit 0 of this register is 0, this field is read-only and shows the strapped ID. When bit 1 of this register is 1, this field is read/write and can be used to assign any valid I2C ID.
			0	DES ID	R/W	0x0	0: Device ID is from IDX strap pin 1: Register I2C device ID overrides strapped value

			3:2	SDA Output Delay	R/W	0x0	SDA output delay This field configures additional delay on the SDA output relative to the falling edge of SCL. Setting this value increases output delay in units of 40 ns. Nominal output delay values for SCL to SDA are: 00: 240 ns 01: 280 ns 10: 320 ns 11: 360 ns

Once the amount of data in the FIFO reaches this threshold, data will begin transmission on the DVP interface. The threshold is in units of FPD-Link III clock cycles. The FIFO has a depth of 256, so setting to 0x40 will set the threshold at 1/4 of the FIFO.

Errors are accumulated over 1/2 of the period of the timer set by the ADAPTIVE_EQ_RELOCK_TIME filed in the AEQ_TEST register. If the number of errors is greater than the programmed threshold (AEQ_ERR_THOLD), the AEQ will attempt to increase the EQ setting. The errors may also be checked as part of EQ setting validation if AEQ_2STEP_EN is set. The following errors are checked based on this three bit field: [2] FPD3 clk1/clk0 errors [1] DCA sequence errors [0] Parity errors
