Start, Device address, R/W = 0, Register address to be read
Restart, Device address, R/W = 1, Data Read, Stop
If no Stop is issued, the Data Read can be continuously performed. If
the register address falls within the range that allows an address auto-
increment, then the register address auto-increments internally after
every byte of data being read. For register address that falls within a
non-incremental address range, the address is kept static throughout
the entire read operations. Refer to the memory map table for the
address ranges that are auto and non-increment.

Write, Stop
If no Stop is issued, the Data Write can be continuously performed. If
the register address falls within the range that allows address auto-
increment, then the register address auto-increments internally after
every byte of data being written in. For those register addresses that
fall within a non-incremental address range, the address is kept static
throughout the entire write operation. Refer to the memory map table
for the address ranges that are auto and non-increment.
