STATEN/
STATSTB
OUTPUT
Status Enable/Status Strobe
- This line pulses low to enable the status word
onto the internal highway for transmission. When in RT mode this line must not
be used to enable data from the subsystem. This line also pulses high, when in
the Bus Control mode, to strobe received status words into the subsystem.
When PASMON is true this line pulses high for Command and Status words.
STAT UPDATE
INPUT
Status Update
- When held low, causes TF or SSF to appear in Status Word
response to Transmit Status or Transmit Last Command issued immediately
after fault occurrence
BITEN/
RMDSTB
OUTPUT
Built In Test Enable/Receive Mode Data Strobe
- This line pulses low when
servicing a valid and legal mode command to transmit the internal BIT word.
This signal is for information only and must not be used to enable data from the
subsystem. This line also pulses high when in the Bus Control mode when
mode data is received to be passed to the subsystem and when data is passed
to the subsystem during PASMON.
DWSYNC
OUTPUT
Data Word Sync
- This line goes low if a data word sync and two Manchester
biphase bits are valid.
CT1990 only.
ENABLE
INPUT
Enable
- When held low, enables Bit Decode, Next Status, and Status Update
program lines.
CMSYNC
OUTPUT
Command Word Sync
- This line goes low if a command word sync and two
Manchester biphase bits are valid.
CT1990 only.
NDRQ
OUTPUT
No Data Required
- This line goes low if the encoder transmit buffer is full i.e.
another word is going to be transmitted. This signal is for information only and
must not be used to enable data from the subsystem.
NEXT STAT
INPUT
Next Status
- When held low, causes TF or SSF to appear in very next Status
Word after fault occurrence (except for Transmit Status or Transmit Last Com-
mand).
PASMON
INPUT
Passive Monitor
- When functioning as a Bus Controller this line acts as a
passive monitor select. The active going edge of this line will cause the
REQBUS lines to be latched and that bus, now selected will be monitored so
long as PASMON remains low. All traffic on the bus will be handed, after
validation, to the subsystem via STATSTB for status and commands words,
and RMDSTB for data words.
BCOPSTB
INPUT
Bus Controller Operation Strobe
- When functioning as a Bus Controller a
low going pulse on this line will initiate the selected bus controller operation on
the requested bus, using BCOPA&B and REQBUSA&B.
RMDSTB
See BITEN/RMDSTB.
BCOPA
INPUT
Bus Control Operation A
- Least significant bit of the bus controller operation
select lines.
BCOPB
INPUT
Bus Control Operation B
- Most significant bit of the bus controller operation
select lines.
REQBUS A
BI-DIRECTIONAL
Request Bus A
- This line, when in RT mode, is the least significant bit of the
bus request lines which specify the origin of the command, i.e. they are
sources. When in BC mode these lines are sinks and specify which bus is to be
used for the next command.
REQBUS B
BI-DIRECTIONAL
Request Bus B
- Most significant bit of the bus request lines. (See above for
description.)
