5 V tolerant pad providing digital I/O functions with TTL levels and hysteresis.
5 V tolerant pad providing digital I/O functions (with TTL levels and hysteresis) and analog input. When configured as a ADC input,
digital section of the pad is disabled.
5 V tolerant pad providing digital I/O with TTL levels and hysteresis and analog output function. When configured as the DAC output,
digital section of the pad is disabled.
Open-drain 5 V tolerant digital I/O pad, compatible with I
functionality. When power is switched off, this pin connected to the I
configuration applies to all functions on this pin.
Pad provides digital I/O and USB functions. It is designed in accordance with the USB specification, revision 2.0 (Full-speed and
Low-speed mode only).

The flashless LPC2420, LPC2460, and LPC2470 use pins P3[15]/D15 and P3[14]/D14 for
configuring the external memory bus during the boot process. These pins are sampled
during Power-on Reset (POR). See
pins.
Table 125. Boot control on pins P3[15]/D15 and P3/14]/D14
During the boot process, external memory banks 0 and 1 are configured with the same
data bus width determined by the setting of the two boot pins P3[15]/D15 and P3[14]/D14.
Unused address pins (A0 when booting from 16-bit wide external memory, A1 and A0
when booting from 32-bit wide memory) are configured as GPIO.
The boot loader remaps the vector table to external memory (see
0x3) and branches to address 0x0. The external boot memory must be connected to chip
select 1 (CS1). Note that CS1 is mirrored onto CS0 because the address mirror bit is set
