EPM3032A, EPM3064A, EPM3128A, and EPM3256A devices have six output enables. EPM3512A devices have
10 output enables.
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 3000A 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.
