8.5.1 Unused GPIO and digital Input Pins

If the pins ALS/GPIO1, GPIO2 or GPIO3 are not used, they can be left open (an internal pulldown, which is enabled by

default, will pull them to GND, ALS/GPIO1 is configured as ADC input). The pins DLS1 and DLS2 should be connected

to VSS, INT can be left open.
