3.4.4.2 AUTOVECTOR INTERRUPT ACKNOWLEDGE CYCLE. When the interrupting
device cannot supply a vector number, it requests an automatically generated vector
(autovector). Instead of placing a vector number on the data bus and asserting DSACK ,
the device asserts AVEC to terminate the cycle. If the DSACK
during an interrupt acknowledge cycle terminated by AVEC , the DSACK signals and
