UOWN
R/W-x
BC7
This bit is ignored unless DTSEN = 1.
UOWN: USB Own bit
0 = The microcontroller core owns the BD and its corresponding buffer; the USB module ignores all
DTS: Data Toggle Packet bit
1 = Data 1 packet
0 = Data 0 packet
Reserved: Maintain as ‘0’
DTSEN: Data Toggle Synchronization Enable bit
1 = Data toggle synchronization is enabled; data packets with incorrect sync value will be ignored
0 = No data toggle synchronization is performed
BSTALL: Buffer Stall Enable bit
1 = Buffer STALL enabled; STALL handshake issued if a token is received that would use the BD in
0 = Buffer STALL disabled
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.
