The operand addresses provided
for
Paging
Error
condition
or
Paging
Queue
Interrupt
condition
on
the
Edit
and
Edit
and
Mark
instructions
are
based on
the
assumption
that
the
number
of
source
field bytes
and
the
number
of
pattern
field bytes
are
equal.
In
any
case where
the
number
of source field bytes is less
than
the
number
of
pattern
field bytes, a false indication
of
a
Paging
Error
or
Paging
Queue
may
have occurred,
and
the ending source field address pro-
vided by
this
Special Function
may
not be correct.
9.
When a
Paging
Error
or
Paging
Queue
Interrupt
occurs, the
Pro-
gram
Counter,
Interrupt
Status
Register,
and
General Purpose
Registers
of
the
Interrupted
State
must
not be altered before the
special function is executed.
10. This Special Function should be used only
if
a
Paging
Queue con-
dition
or
Paging
Error
Interrupt
condition occurs. Otherwise,
the
results
are
unpredictable.
11. The
lSI
field
of
the
current
program
states
ISR
is used to identify
the
Program
State
in which
the
interrupt
occurred
(Program
State
to be analyzed).
