Getting Started
supply voltage and IO supply voltages to be applied in any particular order. However, during the power
ramp up, before the power supplies are stable, there may be an interval when the IO pins are actively
driven. After the power is stable, as long as PORESET is asserted, most IO pins are three-stated. To
minimize the time that IO pins are actively driven, apply core voltage before IO voltage and assert
PORESET before the power supplies fully ramp up.

This section describes how to boot the MPC8308_RDB. The on-board flash memory is preloaded with a
flash image from the factory. Before powering up the board, verify that all the on-board DIP switches and
jumpers are set to the factory defaults according to the settings listed in
Settings,”
