When configured as GPDO, set the OBE bit to 1.IBE22 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 ODE33 When configured as DATA[29] or FEC_RXD[1], clear the ODE bit to 0.HYS44 If external master operation is enabled, clear the HYS bit to 0.0 0 WPE55 Refer to the EBI section for weak pullup settings when configured as DATA[29] or FEC_RXD[1].WPS5WRESET: 0 0 0 0 0 0 0 0 1 1 0 0 0 0 1 1Table 6-34.
