[Edge] indicates the edge of the device on which the pad is located. Valid
edge designations 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 PIC 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 Col-
umn Number.
[A/B] indicates the PIO within the PIC to which the pad is connected.
Some of these user programmable pins are shared with special function pins.
These pin when not used as special purpose pins can be programmed as I/
Os for user logic.
During configuration, the user-programmable I/Os are tri-stated with an inter-
nal pull-up resistor enabled. If any pin is not used (or not bonded to a pack-
age pin), it is also tri-stated with an internal pull-up resistor enabled after
configuration.

Reference clock (PLL) input Pads: ULM, LLM, URM, LRM, num = row from
center, T = true and C = complement, index A, B, C...at each side.
Optional feedback (PLL) input Pads: ULM, LLM, URM, LRM, num = row from
center, T = true and C = complement, index A, B, C...at each side.
Primary Clock Pads, T = true and C = complement, n per side, indexed by
bank and 0,1, 2, 3 within bank.
DQS input Pads: T (Top), R (Right), B (Bottom), L (Left), DQS, num = Ball
function number. Any pad can be configured to be DQS output.
