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.
