Reserved. Unknown During Read.
Host controller buffer access indication. When asserted, it
indicates that currently host controller is accessing data
buffer. It is a status bit reporting to software and software
does not need to take any action.
Host controller new frame. Software does not need to take
any action because it is a status about a new frame that is
generated.
Host controller remote wakeup. Software action when this
bit is asserted is implementation specific. It is a status bit
reporting a transition of internal state.
