6.13.6 IST Flag and Parallel Poll Enable Register (PPE)
Similar to the SRQ, the IST flag combines the complete status information in a single bit.
It can be queried by a parallel poll (see chapter 6.13.20.3, "Parallel Poll", on page 313)
or by the *IST? command.
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 SRE. The IST flag is obtained by ORing all results together.
The PPE can be set by the *PRE command and read by the*PRE? query.
6.13.7 Device Status Register
This register contains information on current device states (CONDition register) or states
that occurred since the last query (EVENt register).
The register can be read by the queries STATus:DEVice:CONDition? or
STATus:DEVice[:EVENt]?.
