When configured as TS, the OBE bit has no effect. When configured as GPO, the OBE bit should be set to one.

When configured as TS or GPO, the IBE bit may be set to one to reflect the pin state in the corresponding GPDI
register. Setting the IBE bit to zero reduces power consumption. When configured as GPI, the IBE bit should be set
to one.

Signal Name Module Description I/O

1
In cases where an I/O function can be either an input or an output, I/O direction is specified using
the IBE and OBE bits. Set IBE = 1 for input or OBE = 1 for output.
2
For I/O functions that change direction dynamically, such as the external data bus, switching
between input and output is handled internally and the IBE and OBE bits are ignored.
