TPS25751: I2Cw command for 4CC task

Part Number: TPS25751

Tool/software:

Dear Sirs and Madams,

We are investigating a 4CC task for the TPS25751.

We performed the I2Cw commands exactly as described in the TRM, but they did not work as expected.

After trying various things, I found that setting INPUT DATAX as shown below worked as intended.

//-----------------------------------------------------------------------

Byte 4 : Data

Byte 3 : Command

Byte 2 : Write byte length

Byte 1 : Slave address

//-----------------------------------------------------------------------

The description in TRM is different from the INPUT DATA X we tested above. Could you please tell me your opinion?

Regards,

Masashi
