DESCRIPTION
O Switched output that delivers 0V, 3.3V, 5V, or high impedance to card
I Logic input that controls voltage of AVPP (see control-logic table)
I Logic input that controls voltage of AVPP (see control-logic table)
I Logic input that shuts down AVPP/AVCC and sets AVPP/AVCC to high-impedance state
I Logic input that controls voltage of AVCC (see control-logic table)
I Logic input that controls voltage of AVCC (see control-logic table)
I 3.3V VCC input for card power and/or chip power if 5V is not present
I 5V VCC input for card power and/or chip power
Ground
