Notes to Table 11–1:
(1) VCCPD can be either 2.5 V or 3.0 V. For a 3.0-V I/O standard, VCCPD = 3.0 V. For a 2.5 V I/O standard and below, VCCPD = 2.5 V.
(2) HardCopy IV E devices do not require Programmable Power Technology.
(3) There is one V_REF pin per I/O bank. You can use an external power supply or a resistor divider network to supply this voltage.
(4) This power pin can be disconnected or remain connected on the board.
