Writing a zero or a one to this bit has no effect.
This bit is cleared after a SETUP packet to indicate that the following packet is an OUT packet.
This bit is set after a SETUP packet to indicate that the following packet is an IN packet.
This bit is set for non-control endpoints, indicating the current bank:
This field may be updated one clock cycle after the RWALL bit changes, so the user should not poll this field as an interrupt bit.
This field is set to indicate the number of busy banks:
