When configured as TA, the OBE bit has no effect. When configured as GPO, set the OBE bit to 1.
IBE

2
When configured as TA, or GPIO, 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
