When the bus mode is set to the local bus 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
Reserved
These bits are always read as 0, and the write value
should always be 0.
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.
