2.
After the above rails rise to 90% of their nominal voltage, the following I/O power rails may rise in any sequence (see
Figure 34): QVDD, NVDD, GVDD1, and GVDD2.
Notes: 1.
If the M3 memory is not used, M3VDD can be tied to GND.
2.
If the HSSI port1 is not used, SXCVDD1and SXPVDD1 must be connected to the designated power supplies.
3.
If the HSSI port2 is not used, SXCVDD2 and SXPVDD2 must be connected to the designated power supplies.
4.
If the DDR port 1 interface is not used, it is recommended that GVDD1 be left unconnected.
5.
If the DDR port 2 interface is not used, it is recommended that GVDD2 be left unconnected.

Reset Guidelines
When a debugger is not used, implement the connection scheme shown in Figure 35.
When a debugger is used, implement the connection scheme shown in Figure 36.
