2 – Peripheral Signals Assignment Table
The SmartFusion2 architecture provides a very flexible schema for connecting peripheral signals to
either MSIOs or the FPGA fabric. Use the signal assignment configuration table to define what your
peripheral is connected to in your application. The assignment table has the following columns
(
Figure 2-1):
MSIO - Identifies the peripheral signal name configured in a given row.
Main Connection - Use the drop-down list to select whether the signal is connected to an MSIO or the
FPGA fabric.
Direction - Indicates if the signal direction is IN, OUT or INOUT.
Package Pin - Shows the package pin associated with the MSIO when the signal is connected to an
MSIO.
Extra Connections - Use the Advanced Options check-box to view the extra connection options:
Select the Fabric option to observe into the FPGA fabric a signal that is connected to an MSIO.
Select the GPIO option to observe an input direction signal - from either the FPGA fabric or an
MSIO - using an MSS GPIO.
