6. The master then sends the 8-bit data, which initializes the base
7. The master repeats the start condition.
8. The master transmits the 7-bit slave address.
9. The master sets the R/W bit = 0 to indicate a write cycle.
10. The addressed slave acknowledges the reception by driving SDA
11. The master transmits the number of the group that it wishes to read,
12. The master issues another start condition.
13. The master transmits the 7-bit slave address.
14. The master sets the R/W bit = 1 to indicate a read cycle.
15. The slave drives SDA LOW to acknowledge.
16. The slave starts transmitting the data, MSB first.
17. The master has to provide the acknowledge by driving SDA LOW
18. In the case of a single read, the master does not drive SDA LOW
19. The master terminates the cycle by issuing a stop condition.

during the ACK cycle after reception of the first byte. The slave
responds to this by relinquishing control of the bus and waiting for
the master to issue a stop condition. For burst reads, the master
drives SDA LOW for each byte it receives during the ACK cycle,
except for the last byte.
