<n>	DigitalIn pin to connect to bus bit <n> (p5-p30, NC)

Note:: It is only required to specify as many pin variables as is required for the bus; the rest will default to NC (not connected)

void mode ( PinMode pull )

Set the input pin mode.

Parameters:

mode	PullUp, PullDown, PullNone

operator int ( )

A shorthand for read()

int read ( )
