1. This is a dual address serial EEPROM.
2. The RTM Bus address can be manually changed through the S1 Switch on RTM. The
default switch configuration will set the address to 0x55. Make sure that the address is
unique to the RTM Bus address when setting the switch.
3. The address of the XMC EEPROM is configured through Geographic Address resistor
on- board.
