6.9 Pin function select register 2 (PINSEL2 - 0xE002C014)
The PINSEL2 register controls the functions of the pins as per the settings listed in
Table 8. The direction control bit in the IODIR register is effective only when the GPIO
function is selected for a pin. For other functions direction is controlled automatically.
Settings other than those shown in the table are reserved, and should not be used.

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 LPC2114/LPC2124 each contain single 10-bit successive approximation analog
to digital converter with four 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.
