I²C read access:

I²C read access also can be used to read one or multiple data bytes in one sequence.

A read sequence consists of a one-byte I²C write phase followed by the I²C read phase. The two parts

of the transmission must be separated by a repeated start condition (Sr). The I²C write phase addresses

the slave and sends the register address to be read. After slave acknowledges the transmission, the

master generates again a start condition and sends the slave address together with a read bit (RW =

1). Then the master releases the bus and waits for the data bytes to be read out from slave. After each

data byte the master has to generate an acknowledge bit (ACK = 0) to enable further data transfer. A

NACKM (ACK = 1) from the master stops the data being transferred from the slave. The slave releases

the bus so that the master can generate a STOP condition and terminate the transmission.

The register address is automatically incremented and, therefore, more than one byte can be

sequentially read out. Once a new data read transmission starts, the start address will be set to the

In this way, repetitive multi-bytes reads from the same starting address are possible.
