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.
