MPC8548E Reset Configuration

The MVME4100 supports the power-on reset (POR) pin sampling method for processor
reset configuration. The states of the various configuration pins on the processor are
sampled when reset is deasserted to determine the desired operating modes.
Combinations of pull-up and pull-down resistors are used to set the options. Some options
are fixed and some are selectable at build time by installing appropriate pull up/pull down
resistor combinations for the board's Bill of Materials. Each option and the corresponding
default setting are described in the following table. Refer to the MPC8548E reference
manual, listed in
79 for additional details and/or programming information.
