SOF after INT has
been delivered.
Bit 0 — Transaction error (IN and OUT)
Bit 1 — Babble (IN token only)

After processing
-
When the frame number of bits DW2[7:3] match the frame number of
the USB bus, these bits are checked for 1 before they are sent for
SOF. For example: When SA[7:0] = 1, 1, 1, 1, 1, 1, 1, 1: send INT
for every
SOF of the entire millisecond. When SA[7:0] = 0, 1, 0, 1,
0, 1, 0, 1: send INT for
SOF0, SOF2, SOF4 and SOF6. When
SA[7:0] = 1, 0, 0, 0, 1, 0, 0, 0 = send INT for every fourth SOF.
