MC864xD Reset Configuration

The MVME7100 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 the proper pull-up/pull-down
