8. EEPROM 24LC04

The AX7103 used on chip of EEPROM, model 24LC04, Capacity of
4Kbit（2*256*8bit）comprise 2 blocks of 256byte, communication by IIC bus.
EEPROM on board is to use to study IIC bus communication method. The I2C signal
of EEPROM connected to BANK14 IO of FPGA. The figure 3-8-1 below showed the
hardware designed schematic of EEPROM.
