EPM7032AE, EPM7064AE, EPM7128A, EPM7128AE, EPM7256A, and EPM7256AE devices have six output enable
signals. EPM7512AE devices have 10 output enable signals.
PIA
When the tri-state buffer control is connected to ground, the output is
tri-stated (high impedance) and the I/O pin can be used as a dedicated
input. When the tri-state buffer control is connected to V
enabled.
The MAX 7000A architecture provides dual I/O feedback, in which
macrocell and pin feedbacks are independent. When an I/O pin is
configured as an input, the associated macrocell can be used for buried
logic.
