bit 7 bit 0

Legend: HSC = Hardware Settable/Clearable bit r = Reserved bit

R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’

-n = Value at POR ‘1’ = Bit is set ‘r’ = Reserved bit x = Bit is unknown

bit 15 UOWN: USB Own bit

0 = The microcontroller core owns the BD and its corresponding buffer; the USB module ignores all

other fields in the BD

bit 14 DTS: Data Toggle Packet bit

(1)

1 = Data 1 packet

0 = Data 0 packet

bit 13-12 Reserved: Maintain as ‘0’

bit 11 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

bit 10 BSTALL: Buffer Stall Enable bit

1 = Buffer STALL enabled; STALL handshake issued if a token is received that would use the BD in

the given location (UOWN bit remains set, BD value is unchanged); corresponding EPSTALL bit

will get set on any STALL handshake

0 = Buffer STALL disabled

bit 9-0 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.

Note 1: This bit is ignored unless DTSEN = 1.
