PA OBE
1
1
When configured as TEA, the OBE bit has no effect. When configured as GPO, set the OBE bit to 1.
IBE
2
2
When configured as TEA 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

3
When configured as TEA and external master operation is enabled, clear the ODE bit to 0.
HYS
