6.3.1.12.20 MPC5553: Pad Configuration Register 58 (SIU_PCR58)
The SIU_PCR58 register controls the pin function, direction, and static electrical attributes of the
DATA[30]_FEC_RXD[2]_CAL_DATA[14]_GPIO[58] pin.

When configured as DATA[30], FEC_RXD[2], or CAL_DATA[14], the OBE bit has no effect. When configured as GPO, set the
OBE to 1.
IBE

When configured as DATA[30], FEC_RXD[2], CAL_DATA[14], or GPO, set the IBE bit to 1 to reflect the pin state in the
corresponding GPDI register. Clearing the IBE bit to 0 reduces power consumption. When configured as GPI, set the IBE to 1.
DSC ODE

When configured as DATA[30] or CAL_DATA[14], clear the ODE bit to 0.
