In I2C protocol every command must have device address, register address, number of bytes to send and receive and length of bytes.

Hi Kish,

The default device address is 0x10 write and 0x11 read. This is explained in Section 9.2 of the TRM.

I understand the default address of the IC.

If I see the sample code given, I do not see device address provided in the command that is why I raised this query.

Where the device address is mentioned? And how its works? Do I need to send multiple commands in sequence?

First command like LPI2C_DRV_MasterSetSlaveAddr(0U, ((uint16_T)8U)) just to acknowledge the device?

Regards,

Kish

TS2 and Rst_Shutdown was not configured for anything still the issues observed.

Next time both pins configured as strong pull down still the issue observed.
