The MPC8308 has two I
connected to following devices.
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
sequencer mode, refer to the MPC8308 reference manual.
There is a PCF8574A I
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
