Part Number: DS90UB954-Q1

Hi team,

I have a question about the register setting order and the target register.

Figures 57 and 58 in the data sheet show the order of register settings.

We think that there are three categories of register settings for the 954.

・The "CSI Tx enable and RX Port Forward" to be set last are only two registers that are 0x33: CSI_ENABLE and 0x20: FWD_PORTx_DIS.

   Is it correct?

・The "Sensor Config" are registers from 0x5B to 0x6C.

   Are there any other applicable registers?

・The "954 Config" are everything that doesn't fit into the above two.

   Is it correct?

Best regards,

Tomaki Yoshida

  • Hello Tomaki,

    You are correct, but "sensor config" is referring to the programming of the remote sensor via the bidirectional control channel (if applicable).

    Hi Casey-san,

    Thank you for your support.

    I understand.

    Basically,  "954 config" is all of the setting of 954 registers.

    That is, after all registers setting in 954 are completed, I2C access to 953 and  remote slave may be performed.

    Finally, enable the 954 RX ports and CSI TX output.

    Is it correct?
