Dual channel inertial sensor

8. The slave transmits an ACK

9. The master transmits a STOP condition

Slave address

Master transmission

Slave transmission

The device automatically increments the register address allowing for multiple register

writes to be completed in one trans-action. In this case, the register write data transfers

are constructed as follows:

1. The master transmits a START condition

2. The master transmits the 7-bit slave address

3. The master transmits a '0' for the Read/Write Bit to indicate a Write operation

4. The slave transmits an ACK

5. The master transmits the register address to be written

6. The slave transmits an ACK

7. The master transmits the data byte to be written to the register address

8. The slave transmits an ACK

9. The master transmits the data byte to be written to the register address +1

10.The slave transmits an ACK

11.Repeat step 9 and step 10 until all registers are written

12.The master transmits a STOP condition

15.6.2 Register read transfers

The device supports I2C register read data transfers. Register read data transfers are

constructed as follows:

1. The master transmits a START condition

2. The master transmits the 7-bit slave address

3. The master transmits a '0' for the Read/Write Bit to indicate a Write operation

4. The slave transmits an ACK

5. The master transmits the register address to be read

6. The slave transmits an ACK

7. The master transmits a repeat START condition

8. The master transmits the 7-bit slave address

9. The master transmits a '1' for the Read/Write Bit to indicate a Read operation

10.The slave transmits an ACK

11.The slave transmits the data from the register addressed

12.The master transmits a NACK

13.The master transmits a STOP condition
