Oldi Deserializers; Readback Restriction - Analog Devices MAX96752 User Manual

The beginning of the register address space for each LUT corresponds to the LSB of the respective color.
The LUT can be reverted to a 1:1 straight color mapping after the random value assignment at power-up. For
example, use the following programming pattern to revert the red color LUT of the oLDI deserializer to 1:1 mapping
values:
• 0x1000 = 0x00
• 0x1001 = 0x01
• 0x1002 = 0x02
• ...
• 0x10FF = 0xFF
Enable the LUT using the LUT_x_EN register bit after programming the LUT registers.
The tables below contain the LUT register information. These include the address range for each LUT and their
corresponding enable bits. After configuring, the incoming pixel data will automatically translate to the new
output LUT values after enabling the LUT enable bit.
Note: LUTs cannot be partially enabled. If color translation is needed, all three LUTs must be enabled. See
LUTs for more information.

Readback Restriction

The following sequence is common in typical use cases:
• Program the LUT translation values.
• Readback the LUT translation values (to ensure proper programming).
• Enable the LUT.
