When configured as DATA[26] or FEC_TX_EN, the OBE bit has no effect.
When configured as GPDO, set the OBE bit to 1.
IBE
2
2
When the pad is configured as an output, set the IBE bit to 1 to reflect 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
