5 A_HNP
Set when Device A is configured, BDISC_ACONN is enabled and has attached pullup during HNP;
cleared by resetting BDISC_ACONN bit in control register 1.
6 B_HNP
Set when Device B is configured, BDISC_ACONN is enabled and has asserted an SE0 during HNP;
cleared by resetting BDISC_ACONN bit in control register 1.
