With this operation the master sends an address and
receives 1 or 2 data bytes from the slave device
(Figure 20). The read byte procedure is as follows:
1) The master sends a START condition.
2) The master sends the 7-bit slave ID plus a write bit (low).
3) The addressed slave asserts an ACK on the data line.
4) The master sends the 8-bit register address.
5) The active slave asserts an ACK on the data line only
6) The master sends a repeated START (Sr).
