I 2 C Interfaces
The MPC8308 has two I 2 C interfaces. On the MPC8308_RDB, I 2 C1 is used as master mode and it is
connected to following devices.
? MCU MC9S08QG8 at address 0x0A.
? Optional DAC AD5301 at address 0x0C.
? PCF8574 I 2 C expander at address 0x39.
? Thermal sensor LM75 at address 0x48.
? Serial EEPROM M24256 at address 0x50.
? Real-time clock DS1339U at address 0x68.
The M24256 serial EEPROM can be used to store the reset configuration word of the MPC8308, as well
as to store the configuration registers values and user program if the MPC8308 boot sequencer is enabled.
By default, the EEPROM is not used and the hard reset configuration words are loaded from local bus flash
memory. For details on how to program the reset configuration word value in I 2 C EEPROM and the boot
sequencer mode, refer to the MPC8308 reference manual.
There is a PCF8574A I 2 C I/O expander on the MPC8308_RDB board to provide general purpose I/O
expansion via the I2C1 interface. The PCF8574A has I2C1 address 0x39 and it is able to detect the board
revision number, which flash is currently used to boot and two reserved bit for future expansion. The bit
definition of the PCF8574A is defined as in Table 3 :
I 2 C2 is connected to the clock generator ICS9FG104 and mini PCI-E socket.
