Normally, a standard communication consists of four parts:
A master-transmitter addressing a slave receiver with a 7-bit address
The transfer direction is not changed
A master reads a slave immediately after the first byte (address)
The transfer direction is changed
Function Description
1) START or Repeated START signal generation
2) Slave address and R/W bit transfer
3) Data transfer
4) STOP signal generation
