PA OBE
1
1
When configured as DATA[21] or FEC_RX_ER, the OBE bit has no effect.
When configured as GPDO (output), set the OBE bit to 1.
IBE
2
2
When the pad is configured as an output, set the IBE bit to 1 to show the pin state in the GPDI register. Clear the IBE bit to 0
to reduce power consumption. When configured as GPDI, set the IBE bit to 1.
DSC ODE

3
When configured as DATA[21] or FEC_RX_ER, clear the ODE bit to 0.
HYS
