INTRODUCTION
This document is the MPC821FADS daughterboard operation guide. The daughterboard
encompasses the MPC821 device along with some necessary logic that must be in close
proximity to the MPC821 and peripherals. These peripherals are dedicated to the MPC821,
but are not necessarily required for any other member of the MPC8xx Family. The
daughterboard has two sets of matching connectors—one set on the print side (on the
bottom of the board) and one on the component side (on the top of the board). Those on the
print side connect to a matching set found on the MPC8xxFADS, while those on the
component side are to serve hardware expansion via a dedicated adaptor. Also a set of logic
analyzer connectors is featured matching the new high-density HP16500 logic analyzer
adaptors to provide fast connection to a logic analyzer while saving board space and
reducing EMI.
