Standard

Group
The
4263B
provides
two
Standard
Operation

|
Operation
Status
Register
group
an
d
Questionable
Status
Register
group
|
which
can
be
accessed
using
the
ST
A
Tus subsystem
commands
.
(Refer
to
ST
A
Tus
subsystem
in
\GPIB
Commands".)
As
a
beginner
,
you will
rarely
need
to
use
this
group
.The
individual bit
assignment of
these registers
are
given
in
\Operation
Status
Register"
and
\Questionable
Status
Register"
later
in this
section.
Each
group
includes
a
condition
register
an
event register
, and
an enable
register
.
(Illustrated
in
Figure
5-5
.)
The
condition
register
reects
the
internal states
of the
4263B.
So each
time the
4263B's
condition
is
changed,
its
condition
bit
is
changed
from
\0" to
\1",
or
from
\1"
to
\0".
The event register's bits correspond to the register's bits
. A transition lter reports an event to
the event register
, when a condition register bit changes from \1" to \0" for all bits except for
bit no
. 8 and 9. F
or bit no's 8 and 9, when a condition register bit changes
from \0" to \1".
The enable register enable
the corresponding bit in the event register to set the status summary
bit, bit 7 or bit
3, of the Status Byte Register
.
