The control byte identifies the slave IC, which is accessed by the master (the digital
transceiver). The digital transceiver writes A0
access (bits A2:A0] are 0). EEPROM pins A2, A1 and A0 must be connected to GND to
enable the EEPROM to respond as a slave to the digital transceiver.
For a write cycle, data bits are driven by the digital transceiver. For a read cycles, these
bits are driven by the EEPROM.
