 -- NC            : No Connect. This pin has no internal connection to the device.
 -- VCCINT        : Dedicated power pin, which MUST be connected to VCC  (3.3V).
 -- VCCIO         : Dedicated power pin, which MUST be connected to VCC  (Refer to
 --                 the table below for voltage).
 -- GND           : Dedicated ground pin. Dedicated GND pins MUST be connected to GND.
 --					It can also be used to report unused dedicated pins. The connection
 --					on the board for unused dedicated pins depends on whether this will
 --					be used in a future design. One example is device migration. When
 --					using device migration, refer to the device pin-tables. If it is a
 --					GND pin in the pin table or if it will not be used in a future design
 --					for another purpose the it MUST be connected to GND. If it is an unused
 --					dedicated pin, then it can be connected to a valid signal on the board
 --					(low, high, or toggling) if that signal is required for a different
 --					revision of the design.
 -- GND+          : Unused input pin. It can also be used to report unused dual-purpose pins.
 --					This pin should be connected to GND. It may also be connected  to a
 --					valid signal  on the board  (low, high, or toggling)  if that signal
 --					is required for a different revision of the design.
 -- GND*          : Unused  I/O  pin.   This pin can either be left unconnected or
 --           	    connected to GND.  Connecting this pin to GND will improve the
 --           	    device's immunity to noise.
 -- NON_MIGRATABLE: This pin cannot be migrated.
