VSS[1]
Ground A1
The VSS[28:1] DC ground pins should be
connected to ground. They provide a ground
reference for the 3.3 V rail. They also provide
a ground reference for the 2.5 V rail.

Notes on Pin Description:
1. All FREEDM-84P672 non-PCI inputs and bi-directionals present minimum
capacitive loading and are 3.3 Volt tolerant. PCI signals conform to the 3.3
Volt signaling environment.
2. All FREEDM-84P672 non-PCI outputs and bi-directionals have 8 mA drive
capability, except the TDO output which has 4 mA drive capability.
3. All FREEDM-84P672 outputs can be tristated under control of the IEEE
P1149.1 test access port, even those which do not tristate under normal
operation. All non-PCI outputs and bi-directionals are 3.3 V tolerant when
tristated.
