BDnSTAT: BUFFER DESCRIPTOR n STATUS REGISTER (BD0STAT THROUGH
BD63STAT), CPU MODE (DATA IS WRITTEN TO THE SIDE)
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
KEN: BD Keep Enable bit
1 = USB will keep the BD indefinitely once UOWN is set (required for SPP endpoint
0 = USB will hand back the BD once a token has been processed
INCDIS: Address Increment Disable bit
1 = Address increment disabled (required for SPP endpoint configuration)
0 = Address increment enabled
DTSEN: Data Toggle Synchronization Enable bit
1 = Data toggle synchronization is enabled; data packets with incorrect Sync value will be
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
0 = Buffer stall disabled
BC9:BC8: Byte Count bits 9 and 8
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.
