Figure 19. SDP Schematic
SPI_SEL1/SPI_SS MUST BE ONLY USED
WITH EXTERNAL SPI FLASH
BMODE1: PULL UP WITH A 10kΩ RESISTOR
TO SET SDP TO BOOT FROM A SPI FLASH
ON THE DAUGHTER BOARD
12C BUS 1 IS COMMON ACROSS BOTH
CONNECTORS ON SDP - PULL UP RESISTORS
REQUIRED (CONNECTED TO BLACKFIN
GPIO - USE 12C_0 FIRST)
VIO: USE TO SET IO VOLTAGE MAX DRAW 20MA: USE ONLY TO POWER THE EEPROM (3MA MAX DRAW)
THE SDP REQUIRES 5V 300MA
VIN: USE THIS PIN TO POWER
THE SDP CONNECTOR IMPLEMENTS THE E13 CONNECTOR SPECIFICATIONS STANDARD. THIS IS A STANDARD FOR USE ACROSS ADI AND CANNOT BE MODIFIED
BOARD ID EEPROM (24LC32)
MUST BE ON I2C BUS 0
MAIN 12C BUS (CONNECTED TO BLACKFIN TWI -
PULL UP RESISTORS NOT REQUIRED)
WHEN USING SPI INTERFACE, BE AWARE OF ADDING A PULL UP
ON THE SPI_SEL_A/B/C LINES THAT ARE ACTIVE LOW ENABLED
SINCE SPI IS A SHARED BUS, ENSURE THAT ANY SPI DEVICE ON DAUGHTER BOARD
IS NOT ACTIVELY DRIVING THE MISO DATA LINE UNLESS PROPERLY ADDRESSED WITH
AN ACTIVE LOW CHIP SELECT. ENSURE ALSO THAT THE SPI CLK LINE IS NOT HELD
HIGH OR LOW BY YOUR BOARD AT POWER UP. FAILURE TO MEET THIS
RESULT TO A NON-FUNCTIONAL SYSTEM.
