reserved.
DMA status: A logic 1 indicates a change in the DMA Status
register.
High Speed Status:.A logic 1 indicates a change from FS to
HS mode (HS connection). This bit is not set, when the system
goes into a FS suspend.
Resume status: A logic 1 indicates that a status change from
‘suspend’ to ‘resume’ (active) was detected.
Suspend status: A logic 1 indicates that a status change from
active to ‘suspend’ was detected on the bus.
Pseudo SOF interrupt: A logic 1 indicates that a Pseudo SOF
or SOF was received. Pseudo SOF is an internally generated
clock signal (FS: 1 ms period, HS: 125 s period) synchronized
to the USB bus SOF/ SOF.
SOF interrupt: A logic 1 indicates that a SOF/ SOF was
received.
Bus Reset: A logic 1 indicates that a USB bus reset was
detected.
