To store and execute TMCL programs a EEPROM is needed. Interconnection between TMCC160
and EEPROM is done via SPI_0 interface. To ensure compatibility between TMCC160 default
firmware and EEPROM, please use dedicated Atmel EEPROM listed below. It is possible to use
TMCC160 internal generated 3.3V supply to power the EEPROM.
