Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Reset
This bit is set to enable Reset signaling on the bus and cleared to end
Reset signaling on the bus.
Resume Signaling
Set by the CPU to generate Resume signaling when the device is in
Suspend mode. The CPU should clear this bit after 20 ms.
Suspend Mode
This bit is written to 1 by the CPU to enter Suspend mode. Writing a 0
does nothing.
Power Down PHY
Set by the CPU to power down the internal USB PHY.
