This bit changes to "1" at the timing of token packet receive end when
buffer respond NAK, of its not ready state, to IN/OUT token of each
endpoint.
The endpoint which occurred the interrupt is checked to see
EPB_NRDY[5:0].
This flag is cleared to clear the status flag of EPB_NRDY[5:0].

000: Powered State
001: Default State
010: Address State
011: Configured State
1xx: Suspended State
Device state can be known.
As to the device state shift, refer to Fig.5 in the later part.
When detect USB reset, this becomes 001: Default state automatically.
When detect suspend, this becomes 1xx: Suspended state automatically.
Whatever the automatic response mode is, this becomes 010: Address
state after executed Set_Address request, and becomes 011: Configured
state after executed Set_Configuration request.
(Write operation is available when S/W control mode is set)
Device state
This bit changes to "1" when received setup packet.
This flag does not the factor of interrupt.
When "0" is written, status flag is cleared .
When "1" is written, flag is not changed .

Can be seen the stage of control transfer.
As to the stage shift of control transfer, refer to Fig.5 in the later part.

Vbus input port
Input data from external Vbus is stored.
0: Vbus input port is "L"
1: Vbus input port is "H"
External Vbus input data is latched by the positive edge of internal clock.
Refer to this bit after enabled internal clock operation.
