This bit must be initialized by the user to the desired value prior to enabling the USB module.
This bit is ignored unless DTSEN = 1.
If these bits are set, USB communication may not work. Hence, these bits should always be maintained as
‘0’.
UOWN: USB Own bit
0 = The microcontroller core owns the BD and its corresponding buffer
DTS: Data Toggle Synchronization bit
1 = Data 1 packet
0 = Data 0 packet
Unimplemented: These bits should always be programmed to ‘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 the
0 = Buffer stall disabled
BC<9:8>: Byte Count 9 and 8 bits
The byte count bits represent the number of bytes that will be transmitted for an IN token or received
during an OUT token. Together with BC<7:0>, the valid byte counts are 0-1023.
