Hi Team
In datasheet it is mentioned to configure ADS7138 to high speed mode by giving codes in I2C frames. How do we need to provide the codes from the master to enable the high speed mode
Thanks

Hi Abishek,
This is part of the I2C specification. High-speed is enabled by sending any of the master codes (0x09, 0b, 0D or 0x0F) specified in the i2c spec (or ADS7138 datasheet). By default all i2c devices are in standard mode.
Hi Tom
Thanks for your reply. We changed the slave address in the driver code of ADS7138 to master code(0x09) since in I2C frame format slave address comes after start bit. when we change the slave address we could not detect the ADC.
Is this the correct way to update the master code?
If we need to update in driver code where we to update the master code(whether in slave address or data bits)
Please confirm the method
Thanks

Hi Abhishek,
The I2C protocol specification provides the sequence of event for switching the I2C bus to high-speed mode. The sequence of events is:
