Array Side Force 0 – In this input mode, the Switch Matrix line is
forced low (logic 0), regardless of the signal on the corresponding I/O
Port. In this mode an optional input enable (IE) can be selected.
A0
Array Side Force 1 – In this input mode, the Switch Matrix line is
forced high (logic 1), regardless of the signal on the corresponding I/O
Port. In this mode an optional input enable (IE) can be selected.
A1
Bidirectional Transceiver with Register Input – This mode
combines Registered Input and buffered Output (OP). This mode
requires a clock source (CLK), and input enable (IE) and output enable
(OE#).
BT & RI
Bidirectional Transceiver with Register Output – This mode
combines Registered Output (RO) and buffered Input (IE). This mode
requires a clock source (CLK), and input enable (IE) and output enable
(OE#).
The output data inversion mode is NOT available to invert the output
signal.
BT & RO
Bidirectional Transceiver with Register I/O – This mode combines
Registered Input (RI) and Registered Output (RO). This mode requires
a clock source (CLK), and input enable (IE) and output enable (OE#).
The output data inversion mode is NOT available to invert the output
signal.
