When configured as DATA[24] or FEC_COL, the OBE bit has no effect.
When configured as GPDO, set the OBE bit to 1.
IBE

2
When the pad is configured as an output, set the IBE bit to 1 to put 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.
