Connection & passing potential
No specific chromatic passing use is established by these notes alone. A passing function requires a starting chord, a destination and voice movement.
Dadd9/A keeps the function of D added ninth. A is the bass; an inversion can smooth a bass line when neighbouring bass notes support it, but is not automatically a passing chord.
