1. The unused VDDI# pins must be connected to VSS through a 10 KΩ resistor. The VDDI# pins can be grouped and connected to
one 10 KΩ resistor or a 10 K Ω resistor can be used for each VDDI# bank, it completely depends on the board layout. For the
previous design the unused VDDI# pins were DNC, and cannot create functionality issue. Microsemi recommends connecting to
Ground to improve the board reliability.
