The
test
may
be looped by specifying
the
desired
number
of
loops in count. Count must be
an
integer
between
I
and
9999
with
I being
the
default.
A space
is
required
before
specifing count. Count must
be specified
whenever
a specific
channel
is selected
with
channel.
The
failure
codes for the
TIC/PIC
cards
are
listed in Appendix
A.
If
a
channel
is
not
specified, all
channels
are
tested.
The
appropriate
test (TIC, PIC,
or
none) is
run
for
each
card
installed
in
the
CPU
and
if
a
failure
occurs,
the
failure
code is
printed
on
the
System Console
next
to
the
card
description.
The
CHANNEL
test
performs
the
TIC
test
and
the
PIC test.
The
TIC test has six sections:
•
lnit
cher:k.
Perform
an
initialization
uf
the
TIC
and
tl'st
that
the
registers
contain
the
proper
data.
• Rasic
I/O
<'::,erations. Issue ORn, IPOLL, SMSK,
and
RMSK
and
venfy
that
they
respond
properly.
..
Port
register tesls.
Write
patterns
to
registers
0-7
of
ports
0-7
and
verify
the
data
.
..
Diagnostic loopback using
DMA
sequencer
ROM.
•
Initiate
PCC tests on all 8 ports.
•
Perform
DMA
data
loopback test on all 8 ports.
In
addition
the
console TIC
is
both
speed sensed
and
communication
lines
are
tested
with
the local console.
The
PIC test has nine sections:
•
Init
check.
Perform
an
initialization
of
the
PIC
and
test
that
the
registers
contain
the
proper
data.
• Basic
I/O
operations. Issue OBII, IPOLL, SMSK,
and
RMSK
and
verify
that
they
respond
properly
.
..
Test
the
ABI
status
register (PIC register I).
• Test
the
ABI
interrupt
and
interrupt
mask registers (PIC registers 2
and
3,
respectively).
• Test PIC registers 4
and
5 using
data
patterns.
•
Test
PIC
register
6.
• Test PIC register
7.
~
Test PIC registers
8,
9,
and
A using
data
patterns.
• Fill ABI
FIFO
and
do
DMA
to
memory
and
DMA
from
memory. Test PIC registers associated
with
DMA
transfers.
