440GR – PPC440GR Embedded Processor
Preliminary Data Sheet
Revision 1.16 – July 19, 2006
Multimode Signals
In some cases (for example, Ethernet) the function of a pin may vary with different modes of operation. When a pin
has multiple signal names assigned to distinguish different modes of operation, all of the names are shown.
Strapping Pins
One group of pins is used as strapped inputs during system reset. These pins function as strapped inputs only
during reset and are used for other functions during normal operation (see “Strapping” on page 79). Note that
these are not multiplexed pins since the function of the pins is not programmable.
Reserved Pins
The balls marked Reserved on this chip are not functional. However, most of the reserved balls cannot be left
unconnected. Connect the balls shown in Table 6 as indicated:
