PIN DESCRIPTIONS (CONTINUED)
NOTES:
1. All CMOS pins should remain unchanged. CMOS format means that the pin is intended to be tied directly to V
2. All unused outputs may be left floating.
3. These pins are for the JTAG port. Please refer to pages 36-40, Figure 7-9 for JTAG information.

These are V
This pin should be tied to the desired voltage rail for providing to the output drivers. Nominally 1.5V
or 1.8V for HSTL, 2.5V for LVTTL.
These ground pins are for the core device and must be connected to the GND rail.
This is a Voltage Reference input and must be connected to a voltage level determined in the Voltage
Recommended DC Operating Conditions section. This provides the reference voltage when using
HSTL class inputs. If HSTL class inputs are not being used, this pin must be connected to GND.
CC
core power supply pins and must all be connected to a +2.5V supply rail.
