8.0. Serial EEPROM
EEPROM (Electrically Erasable Programmable Read-Only Memory) is a built-in memory module used to store data that must be
saved when power goes off. The 24AA01 circuit can store up to 1Kbit data and uses serial I
for communication with the microcontroller. In order to enable connection between EEPROM and microcontroller, it is necessary to set
switches 5 and 6 on the DIP switch SW12 to ON position.

9.0. Voltage Reference
The BIGPIC6 development system provides an MCP1541 circuit which generates the voltage reference used for A/D conversion. The
value of the voltage reference is 4.096V and it is brought to the microcontroller via the RA3 pin.
