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

100 = A11:2 are address lines.

001 = A3:2 are address lines. 101 = A15:2 are address lines.

010 = A5:2 are address lines. 110 = A19:2 are address lines.

011 = A7:2 are address lines. 111 = A23:2 are address lines.

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 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, 16, or 32 bits wide.

6.10 General purpose parallel I/O

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.

6.10.1 Features

• Direction control of individual bits.

• Separate control of output set and clear.

• All I/O default to inputs after reset.

6.11 10-bit A/D converter

The LPC2210/2220 contains a single 10-bit successive approximation analog to digital

converter with eight multiplexed channels.

6.11.1 Features

• Measurement range of 0 V to 3 V.

• Capable of performing more than 400,000 10-bit samples per second.

• Burst conversion mode for single or multiple inputs.

• Optional conversion on transition on input pin or Timer Match signal.
