Board ID EEPROM (24LC64) must be on I2C bus 0, address is at user discretion
Main I2C bus (Connected to blackfin TWI - Pull up resistors not required)
I2C bus 1 is comm on across both connectors on SDP - Pull up resistors required
Schematic Part B
3.3V_BF
3.3V_BF
(connected to blackfin GPIO - use I2C_0 first)
VIO: USE to set IO voltage max draw 20mA
