hi 

There are two questions about DS90UB960-Q1:

1. When I want to enable 1 Camera, what is my I2C write sequence? (Complete write sequence)

2. When I want to enable 2 cameras or more, what is my I2C write sequence? (Complete write sequence)

    Hi Ben,

    Assuming you are using the 953/935 serializers. Here are the registers you can set:

    - Des reg 0x4C: Select the right RX port to write

    - Des reg 0x58: check back channel (if MODE is strapped correctly, it should have the right back channel)

    - Set/Check real I2C addresses

    - Reg 0x5B SER DEVICE ID: Set the real serializer I2C address. This is typically loaded already

    - Reg 0x5D SlaveID[0]: Set the real CMOS sensor I2C address

    - Reg 0x5C SER_ALIAS_ID: Set the alias serializer I2C address

    - Reg 0x65 SLAVE_ALIAS_ID[0] (camera alias ID): Set the alias CMOS sensor I2C address

    Reg 0x4C can be used to select how many ports are being written.

    Best,
