MPC859T Port Assignments
Note
Many of the pins on the MPC859T have multiple functions.
Where a particular pin function is used in the ASIF application,
this is indicated in bold text; unused functions or unused pins are
in plain text. This table is sorted by pin name order; where a pin
has multiple function names, these are listed in the order shown
on the schematic. This table also lists the UTOPIA interface pin
names, but, for clarity, these are not shown on the schematic.
