IST Flag and Parallel Poll Enable Register (PPE)
Similar to the service request (SRQ), the IST flag combines the complete status infor-
mation in a single bit. It can be queried by a parallel poll or by
.
The parallel poll enable register (PPE) determines which bits of the STB affect the IST
flag. The bits of the STB are ANDed with the corresponding bits of the PPE; bit
6 is
also used, in contrast to the service request enable register. The IST flag is obtained
by
ORing
all results together.
