Description
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 to A2 are address
lines.
010 = A5 to A2 are address
lines.
011 = A7 to A2 are address
lines.

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 MB each with byte lane enable control)
simultaneously. Each memory bank is capable of supporting SRAM, ROM, flash EPROM,
burst ROM memory, or some external I/O devices.
Each memory bank may be 8-bit, 16-bit, or 32-bit 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.
The LPC2210/2220 each contain a single 10-bit successive approximation ADC with eight
multiplexed channels.
