[Edge] indicates the edge of the device on which the pad is located. Valid edge designa-
tions are L (Left), B (Bottom), R (Right), T (Top).
[Row/Column Number] indicates the PFU row or the column of the device on which the
PIO Group exists. When Edge is T (Top) or (Bottom), only need to specify Row Number.
When Edge is L (Left) or R (Right), only need to specify Column Number.
[A/B/C/D/E/F] indicates the PIO within the group to which the pad is connected.
Some of these user programmable pins are shared with special function pins. When not
used as special function pins, these pins can be programmed as I/Os for user logic.
During configuration of the user-programmable I/Os, the user has an option to tri-state the
I/Os and enable an internal pull-up resistor. This option also applies to unused pins (or
those not bonded to a package pin). The default during configuration is for user-program-
mable I/Os to be tri-stated with an internal pull-up resistor enabled. When the device is
erased, I/Os will be tri-stated with an internal pull-up resistor enabled.
Global RESET signal (active low). Dedicated pad, when not in use it can be used as an I/O
pin.
TSALL is a dedicated pad for the global output enable signal. When TSALL is high all the
outputs are tristated. It is a dual function pin. When not in use, it can be used as an I/O pin.
No connect.
GND - Ground. Dedicated pins.
VCC - The power supply pins for core logic. Dedicated pins.
VCCAUX - the Auxiliary power supply pin. This pin powers up a variety of internal circuits
including all the differential and referenced input buffers. Dedicated pins.

Reference clock (PLL) input Pads: [LOC] indicates location. Valid designations are ULM
(Upper PLL) and LLM (Lower PLL). T = true and C = complement.
Optional feedback (PLL) input Pads: [LOC] indicates location. Valid designations are ULM
(Upper PLL) and LLM (Lower PLL). T = true and C = complement.
Primary Clock Pads, n per side.
