Hi Thrimurthi,

--The FX3 device supports associating a preamble with a maximum length of8 bytes to any I2C data transfer. This allows the user to specify a multi-byte preamble which covers the slave address, device specific address fields and then initiate the data transfer.

---No need to set start bit and stop bit for repeated write operation just change the slave address write operation.

Regards,

Anil Srinivas.
