AIN5.
Controls whether P3.0/A0 is a port pin (0) or an address line (1).
Controls whether P3.1/A1 is a port pin (0) or an address line (1).
Controls the number of pins among P3.23/A23/XCLK and P3.22:2/A2.22:2 that
are address lines:
000 = None
001 = A3:2 are address
lines.

6.10.1 Features
6.10 General purpose parallel I/O
6.9 External memory controller
The external Static Memory Controller is a module which provides an interface
between the system bus and external (off-chip) memory devices. It provides support
for up to four independently configurable memory banks (16 MBytes each with byte
lane enable control) simultaneously. Each memory banks is capable of supporting
SRAM, ROM, Flash EPROM, Burst ROM memory, or some external I/O devices.
Each memory bank may be 8, 16, or 32 bits wide.
Device pins that are not connected to a specific peripheral function are controlled by
the GPIO registers. Pins may be dynamically configured as inputs or outputs.
Separate registers allow setting or clearing any number of outputs simultaneously.
The value of the output register may be read back, as well as the current state of the
port pins.

Direction control of individual bits.
Separate control of output set and clear.
All I/O default to inputs after reset.
100 = A11:2 are address lines.
101 = A15:2 are address lines.
110 = A19:2 are address lines.
111 = A23:2 are address lines.
