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 DAC 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 (LPC2378 only). It is designed in accordance with the USB specification, revision 2.0
(Full-speed and Low-speed mode only).
5 V tolerant pad with 5 ns glitch filter providing digital I/O functions with TTL levels and hysteresis.
5 V tolerant pad with 20 ns glitch filter providing digital I/O function with TTL levels and hysteresis.
Pad provides special analog functionality.
When the main oscillator is not used, connect XTAL1 and XTAL2 as follows: XTAL1 can be left floating or can be grounded (grounding
is preferred to reduce susceptibility to noise). XTAL2 should be left floating.
