Table 5: User I/Os
Please note that not all I/Os listed in Table 5 are available on the module connector. Certain user I/Os on the
module connectors can be connected to various MPSoC I/Os, depending on the product variant. Section
2.9.2 lists and describes the connectivity for these pins for each assembly variant. The multi-use signals on
the module connector are not named according to the naming convention described above.
The multi-gigabit transceiver (MGT) are described in section 2.10.
2.9.2 I/O Pin Exceptions
The I/O pin exceptions are pins with special functions or restrictions (for example, when used in combination
with certain Mercury boards they may have a specific role).

HD = high density pins, HP = high performance pins; Refer to the Zynq UltraScale+ MPSoC Overview [23] for details.
