6.8.2.3 Master Transmits and Receives Data to & from the Same Slave Device
The Initial operation of this data transfer format is the same as explained in Section
6.8.2.1 above. Then the Master device starts to transmit the data to the Slave device.
When the Slave device receives an Acknowledge or Not Acknowledge that is
followed by repeat START (Sr), the operation “Master-Receiver Reads from Slave-
Transmitter with 10-bit Slave Address” described in the preceding Section 6.8.2.2, is
then performed.

6.8.2.4 Master Device Transmits Data to Two or More Slave Devices with 10 & 7
For 10-bit Slave address transmittal, the initial operation of this data transmit format is
the same as explained in the Section 6.8.2.1 above which describes how to transmit
the data to Slave device. After the Master device completed the initial transmittal,
and want to continue transmitting data to another device, the Master needs to
address each of the new Slave devices by repeating the initial operation mentioned
above.
