When the bus mode is set to DU via the bus mode pins (MODE11 and MODE12), the
pin is initially used as a general-purpose input, and the pin status is read from this
register.

Description
These bits store output data of a pin which is used as a
general-purpose output port. When the pin functions as
a general-purpose output port, reading the port will read
out the value of the corresponding bit of this register.
When the pin functions as a general-purpose input port,
reading the port will read out the status of the
corresponding pin.
