Note 2 : Parallel Port pins when MODE0 = 1
When the device operates as a single function device (MODE0 pin = ‘1’), in addition to function 1 (the parallel port) not being
made available to PCI configuration accesses, all of the parallel port bi-directional pins and open-drain output pins are forced into
their input modes. This means that when MODE0 = 1, as well as the standard parallel port inputs needing a tie to ground to
prevent floating inputs, all of the bi-directional and open-drain parallel port pins also require a tie to ground. This affects all of the
pins of the parallel port with the exception of the pin “l(fā)ocal_trans_en” that remains as an output.
Note 3: Power & Ground
There are several types of VDD and VSS in this design, providing not only power for the internal (core) and I/O pad area but also
special power lines to the PCI I/O buffers. These power rails are not connected internally. This precaution reduces the effects of
simultaneous switching outputs and undesirable RF radiation fromthe chip. Further precaution is taken by segmenting the GND
and VDD rails to isolate the PCI and UART pins.
