Figure 5-49. I2C Read
In the case of an I2C register write, if the master does not issue a STOP condition, then the device enters
auto-increment mode. So in the next eight clocks, the data on SDA is treated as data for the next
incremental register.
Similarly, in the case of an I2C register read, after the device has sent out the 8-bit data from the
addressed register, if the master issues an ACKNOWLEDGE, the slave takes over control of the SDA bus
and transmits for the next eight clocks the data of the next incremental register.
