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