I 2 C
The MPC8349E has two I 2 C interfaces. On the MPC8349E-mITXE board, the MPC8349E acts as I 2 C
master for both I 2 C buses (I2C1 and I2C2). I2C1 is connected to the M24256 serial EEPROM, and I2C2
is connected to the DDR DIMM module SPD (serial presence detect) EEPROM, the two PCF8574 I 2 C
expanders, the DS1339 RTC (real time clock) and the I 2 C interface of the MC9S08QG8.
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 2 C EEPROM and the boot sequencer mode, please refer to
the MPC8349ERM. The I 2 C address of the M24256 EEPROM on I2C1 bus is 0x50.
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 2 C address of the DDR SPD EEPROM on I2C2 bus is 0x51.
There are two PCF8574A I 2 C I/O expander on the MPC8349E-mITXE board to provide general purpose
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
