When configured as DATA[19], FEC_RX_CLK, or CAL_DATA[3], the OBE bit has no effect. When configured as GPO, set the
OBE bit to 1.
IBE

When configured as DATA[19], FEC_RX_CLK, CAL_DATA[3], or GPO, set the IBE bit to 1 to reflect the pin state in the
corresponding GPDI register. Clear the IBE to 0 to reduce power consumption. When configured as GPI, set the IBE bit to 1.
DSC ODE
