To restore the switches to their factory default settings, perform these steps:
1. Set the DIP switch bank (SW2) to match Table 3–1 and Figure 3–1 .
In the following table, ON indicates the switch is to the left according to the board
orientation as shown in
Figure 3–1 .
2. Set the DIP switch bank (SW3) to match Table 3–2 and Figure 3–1 .
In the following table, up and down indicates the position of the switch with the
board orientation as shown in
Figure 3–1 .
Important: The default MSEL pin settings are set to all zeroes (ON) to select the fast
passive parallel x16 mode. For power-up configuration from MAX V and CFI
flash, ensure that the MAX V design uses this same mode as does in the design in
the \kits\arriaVST_5astfd5kf40es_soc\examples\max5 directory.
