The bits are numbered in descending order of receipt, starting with bit
31 as the MSB of Byte 1, down to bit 0 as the LSB of Byte 4. A "0" in
the bit position disables automatic output of the associated packets; a
"1" in the bit position makes the associated packets available for
automatic output. Table A-77 describes the packets affected by
each bit.
