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.
Session Disconnect
Set when a device disconnect is detected.
Session Connect
Set when a device connection is detected.
Start of Frame
Set when a new frame starts.
Babble Detected
Set when babble is detected. Only active after first SOF has been sent.
Resume Signal Detected
Set when Resume signaling is detected on the bus while the USB
controller is in Suspend mode.
This can only be used if the USB's system clock is enabled. If the user
disables the clock programming, the USBDRCRIS, USBDRCIM, and
USBISC registers should be used.
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.
