BOENRGB
enables output port B to be set to high-impedance
0 = active signal
1 = high-impedance

AOENRGB
enables output port A to be set to high-impedance
0 = active signal
1 = high-impedance
2
OROEN
enables outputs Out Of Range to be set to high-impedance
0 = active signal
1 = high-impedance
1
TOUTERGB
denes if the test mode of the output buffer is active or not
0 = mode normal
1 = mode test
0
TOUTSRGB
denes the state of the output in test mode
0 = forces output to LOW
1 = forces output to HIGH
