Reading from multiple registers with incremental addressing
Reading from multiple registers starts in the same way like reading from a single register. As
soon as the first register is read, the register address is automatically increased. If the
master generates an acknowledge pulse after receiving the data from the first register, then
reading of the next register can start immediately without sending the device address and
the register address again. The last acknowledge pulse before the STOP bit is not required.
