BU-61559 Series
C-12/02-300
16 MHz clock input.
CLOCK IN (I)
32
56
Master Clear. Negative true Reset
input, normally asserted low following
power turn-on.
MSTCLR (I)
71
55
In Command. In BC mode, asserted
low throughout processing cycle for
each message. In RT mode, asserted
low following receipt of Command Word
and kept low until completion of current
message sequence. In Monitor mode,
goes low following MONITOR START
command, kept low while monitor is on-
line, goes high following RESET com-
mand.
INCMD (O)
70
57
The 1553 Channel A and/or Channel B
transmitters may be inhibited by assert-
ing the respective TX_INH input(s) high.
*
TX_INH_A (I)
76
45
TX_INH_B (I)
57
34
If this input is asserted low the
Subsystem Flag bit will be set in the
BU-61559's RT Status Word. A low on
the SSFLAG input overrides a logic “1”
of the respective bit (bit 8) of
Configuration Register #1.
SSFLAG (I)
37
46
In BC or RT modes, this output will be
asserted as a low level following a word
or format error and remain low until the
start of the next message.
MSG_ERR (O)
12
23
In RT/transparent mode, this output will
pulse low for nominally 62.5 ns (signal
is one clock cycle wide) and occurs in
the middle of the transfer cycle, coinci-
dent with the MEMWR pulse for writing
the command word to RAM.
In RT/transparent mode, this output will
pulse low for nominally 62.5 ns (signal
is one clock cycle wide) and occurs
during the third of four clock cycles dur-
ing a data word write cycle, in the same
time frame that MEMWR writes the
received data word to RAM.
CMD_STR (O)
13
25
RX_DTA_STR
(O)
52
24
In RT/transparent mode, this output will
pulse low for nominally 62.5 nsec (sig-
nal is one clock cycle wide) and occurs
during the third of four clock cycles dur-
ing a data word read cycle.
TX_DTA_STR
(O)
53
26
SIGNAL NAME
PIN NO.
DESCRIPTION
DIP
FLAT
MISCELLANEOUS (16)
Broadcast Enable. If connected to logic
1, the BU-61559 will recognize RT
Address 31 as the broadcast address. If
connected to logic 0, RT Address 31
may be used as a discrete RT address.
BRO_ENA (I)
54
28
Broadcast Command received is an
active low signal that occurs 1.35 to
2.25 μs following the mid-parity bit
crossing of a received broadcast com-
mand word that remains low until
receipt of a subsequent command word
to the BU-61559’s own RT address.
BCSTRCV (O)
16
31
Illegalization Enable. If connected to
logic 1, designates shared RAM
addresses 0300-03FF to be dedicated
for command illegalization in RT mode.
If set to logic 0, illegalization is disabled
and addresses 0300-03FF may be
used for stack or message data. Has no
effect in BC or MT modes.
ILLENA (I)
17
33
External Time Tag Clock input. For
BC/RT modes. Use may be designated
by means of Configuration Register # 2.
If not used, should be connected to
+5V or ground.
TAG_CLK (I)
15
29
In RT mode, is updated following every
valid, nonbroadcast message. Will be
asserted low if the RT fails its loopback
test (invalid or mismatch to last trans-
mitted word) or if a 768 μs timeout con-
dition occurs. Cleared by reset or as a
result of next valid, non-broadcast mes-
sage.
RT_FAIL (O)
55
30
Active low input used to control RT
FLAG bit in RT Status Word. If RTFAIL
is low, the RT FLAG bit will be set. May
be connected to RTFAIL.
RTFLAG (I)
56
32
SIGNAL NAME
PIN NO.
DESCRIPTION
DIP
FLAT
MISCELLANEOUS (16) (CONT)
* The operation of the TX_INH_A/B inputs also effects the operation of the BC off-
line self test. If the inhibit is high when an off-line BC self test is run, a “l(fā)oop test”
failure will occur.
