UOWN: USB Own bit
1 = The USB module owns the BD and its corresponding buffer; the CPU must not modify the BD or
DTS: Data Toggle Packet bit
1 = Data 1 packet
0 = Data 0 packet
PID<3:0>: Packet Identifier bits (written by the USB module)
In Device mode:
Represents the PID of the received token during the last transfer.
In Host mode:
Represents the last returned PID or the transfer status indicator.
BC<9:0>: Byte Count bits
This represents the number of bytes to be transmitted or the maximum number of bytes to be received
during a transfer. Upon completion, the byte count is updated by the USB module with the actual
number of bytes transmitted or received.
