Pin Description
Signal
Direction
Signal Description
RX DATA 0/1
INPUT
Positive Data In.
This should be a TTL description of the positive, half of the
Manchester code data on the bus. It should be driven to a logic level “1” when
a predetermined positive threshold is exceeded on the bus.
RX DATA 0/1
INPUT
Negative Data In.
This should be a TTL description of the negative half of the
Manchester code data on the bus. It should be driven to a logic level “1” when
a predetermined negative threshold is exceeded on the bus.
TX INHIBIT 0
OUTPUT
Transmitter Inhibit Bus 0.
Normally high. Goes low when the transmitter is
transmitting. Should be used to Inhibit the bus "0" driver.
TX INHIBIT 1
OUTPUT
Transmitter Inhibit Bus 1.
Normally high. Goes low when the transmitter is
transmitting. Should be used to Inhibit the bus "1" driver.
TX DATA
OUTPUT
Positive Data Out
- When this signal goes high the bus should be driven
positive.
TX DATA
OUTPUT
Negative Data Out
- When this signal goes high the bus should be driven
negative.
RTAD 0-4
INPUT
RT address lines
- These should be hardwired by the user. RTAD4 is the most
significant bit.
RTADPAR
INPUT
RT address parity line
- This must be hardwired by the user to give odd parity.
BIT DECODE
INPUT
Built-ln Test Decode
- When held low, prevents resetting TXTO Bit, HSFAIL
Bit, and LTFAIL Bit in the BIT Word (as well as TF and SSF Bits in the Status
Word) upon receipt of a Transmit Bit Word Mode Command.
BCSTEN 0/1
INPUT
Broadcast command enable Bus 0/1
- When low the recognition of
broadcast command is prevented on both Bus 0 and 1.
CT1991 only.
BCSTEN 0
INPUT
Broadcast command enable Bus 0
- When low the recognition of broadcast
command is prevented on Bus 0.
CT1990 only.
BCSTEN 1
INPUT
Broadcast command enable Bus 1
- When low the recognition of broadcast
command is prevented on Bus 1.
CT1990 only.
6MCK
INPUT
6 Megahertz master clock.
IH 08 (LSB)
IH 19
IH 210
IH 311
IH 412
IH 513
IH614
IH715 (MSB)
BI-DIRECTIONAL
Internal Highway
- Bi-directional 8 bit highway on which 16 bit words are
passed in two bytes. IH 715 is the most significant bit of each byte, the most
significant byte being transferred first. The highway should only be driven by
the subsystem when data is to be transferred to the RT.
DTRQ
OUTPUT
Data Transfer Request
- Goes low to request a data transfer between the
ASIC and subsystem. Goes high at the end of the transfer.
DTAK
INPUT
Data Transfer Acknowledge
- Goes low to indicate that the subsystem is
ready for the data transfer.
IUSTB
OUTPUT
Interface Unit Strobe
- This is a double pulse strobe used to transfer the two
bytes of data
H/L
OUTPUT
High/Low
- Indicates which byte of data is on the internal highway. Logic level
"0" for least significant byte.
GBR
OUTPUT
Good Block Received
- Pulses low for 500ns when a block of data has been
received by the ASIC and has passed all the validity and error checks.
