All pins are three-stated during and immediately after reset,
with the exception of the external memory interface. On the
external memory interface, the control and address lines are
driven high during reset unless the BR pin is asserted.
All I/O pins have their input buffers disabled, with the exception
of the pins noted in the data sheet that need pull-ups or pull-
downs if unused.
