ERROR INTERPRETATION

INTRODUCTION
The TICDIAG traps many errors
that
would normally result in interrupts and system failures. In many
cases, the TICDIAG creates the circumstances in which these errors occur.
Each failure detected by
the
TICDIAG results in an
error
message. The
error
message contains
the
following information:
1)
the
test
that
detected the error;
2)
the symptoms of the error
(e.
g.
incorrect register contents);
3)
the
functional block of circuitry
that
failed; and
4)
an
error
number
that
indexes the possible failed component(s).
EXAMPLE:
Lynx
bus
logic
not
in
state
000
after
INIT.
Current
State
is:
001.
LBus
State
Machine/Reset
Logic
failure.
Error
number
22.
Lynx
Bus
Sequencing
test
failed.
If an
error
occurs during execution
of
the TICDIAG a,ld it
is
not an
error
trapped by the TICDIAG
program, a
DUS
error
message
is
displayed. This should only occur under unusual circumstances (e.g.,
some
part
of
the system
other
than
the TIC under test failed to function properly).
