VIN: Use this pin to power the SDP requires 4-7V 200mA

VIO: USE to set IO voltage max draw 20mA

Board ID EEPROM (24LC64) must be on I2C bus 0, address is at user discretion

I2C bus 1 is common across both connectors on SDP - Pull up resistors required

BMODE1: Pull up with a 10Kresistor to set SDP to boot from a SPI FLASH on the daughter board

(connected to blackfin GPIO - use I2C_0 first)

Main I2C bus (Connected to blackfin TWI - Pull up resistors not required)
