MPC8349E-mITXE Board
A boot Flash selector jumper allows the user to select between two different boot images in each bank of
Flash memory.

The MPC8349E has two I
master for both I
is connected to the DDR DIMM module SPD (serial presence detect) EEPROM, the two PCF8574 I
expanders, the DS1339 RTC (real time clock) and the I
The M24256 serial EEPROM can be used to store the reset configuration word of the MPC8349E, as well
as storing the configuration registers values if boot sequencer of MPC8349E is enabled. If user wants to
load the reset configuration word from the I2C1 M24256 EEPROM, the jumper J22 should be set to
ABCDEFGH=01011110, with 1=jumper removed and 0=jumper installed. For more details on how to
program the reset configuration word value in I

The DDR SPD EEPROM is connected to the I2C2 of MPC8349E. The bootload program optionally reads
the SPD EEPROM data to determine the DDR DIMM physical structure (e.g. number of rows and
columns), the DDR timings (e.g. CAS latency, re-fresh timing), and setup the configuration registers of
the MPC8349E DDR memory controller. The I
There are two PCF8574A I
I/O expansion via the I2C2 interface. The first PCF8574A (U8) has I2C2 address 0x38 and it is able to
control the Green LED (D1) and Yellow LED (D2), set the VSC8201 to powerdown mode, set the logic
level of PCI_PME signal of the miniPCI card, and enable the LCD interface of the MPC8349E-mITXE
board. The bit definition of this PCF8574A (U8) is defined as in
