Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

‘1’ = Bit is set

U = Unimplemented bit, read as ‘0’

‘0’ = Bit is cleared

x = Bit is unknown

bit 7

bit 6

bit 5-2

bit 1-0

UOWN: USB Own bit

1 = The SIE owns the BD and its corresponding buffer

0 = Refer to Register 26-5.

Reserved: Not written by the SIE

PID<3:0>: Packet Identifier bits

The received token PID value of the last transfer (IN, OUT or SETUP transactions only).

BC<9:8>: Byte Count 9 and 8 bits

These bits are updated by the SIE to reflect the actual number of bytes received on an OUT transfer

and the actual number of bytes transmitted on an IN transfer.
