Figure 9. I2C Write Operation
A read operation is performed in two stages. A data write is used to set the register address, then a data read is
performed to retrieve the data from the set address. A read burst operation is also supported. This is shown in
Figure 10. I2C Read Operation
AC and DC electrical specifications for the SCL and SDA pins are shown in Table 7. The timing specifications and
timing diagram for the I2C bus is compatible with the I2C-Bus Standard. SDA timeout is supported for compatibility
with SMBus interfaces.
