READ MODES
Read modes are referred to as traditional because the first two
bytes for all three cases are dummy bytes that function to place
the pointer toward the correct register. This is the reason for the
repeat start. In theory, this step can be avoided if the user is
interested in reading a register that was previously written to.
For example, if the EEPROM was just written to, the user can
skip the two dummy bytes and proceed directly to the slave
address byte followed by the EEPROM readback data.
