6.2 Pin description
I/O pins on the LPC178x/7x are 5 V tolerant and have input hysteresis unless otherwise
indicated in the table below. Crystal pins, power pins, and reference voltage pins are not
5 V tolerant. In addition, when pins are selected to be ADC inputs, they are no longer 5 V
tolerant and the input voltage must be limited to the voltage at the ADC positive reference
pin (VREFP).
All port pins Pn[m] are multiplexed, and the multiplexed functions appear in Table 3 in the
order defined by the FUNC bits of the corresponding IOCON register up to the highest
used function number. Each port pin can support up to eight multiplexed functions.
IOCON register FUNC values which are reserved are noted as ‘R’ in the pin configuration
table.
