Serial EEPROM: Address 0xA8
The serial EEPROM function allows EEPROM memory to be read and written. The
data shown is the actual data that is written on the PIC MCU data EEPROM.

Thermal Management: Address 0xA6
The Temperature Management function provides control over fan controller settings.
The fan speed output is based on upper and lower temperature set points and ambient
temperature. See how adjusting these temperature set points and ambient temperature
affect fan speed. In order to measure ambient temperature, JP202 must connect the
middle pin to the pin labeled “MCP9700.” The JP202 jumper can also be moved to con-
nect the POT pin to the middle pin. This can allow the sweeping of temperatures in the
full range of temperature values.
