Plainview NY (516) 694-6700

CLOCK

6 MHz Master Clock.

DATA CHA

DATA CHANNEL A. (BUS 0). This is the combined signals, RX

Data In and TX Data Out, that connect to the IN phase primary

terminal of the Bus Transformer.

DATA CHA

DATA CHANNEL A. (BUS 0) This is the combined signals RX

Data In and TX Data Out, that connect to the OUT of phase

primary terminal of the Bus Transformer.

DATA CHB

Same as DATA CHA, except for Channel B. (BUS 1).

DATA CHB

Same as DATA CHA, except for Channel B. (BUS 1).

DB0

I/O DATA BUS. Data Bus for all SUBSYSTEM

READ and WRITE OPERATIONS.

16 BIT MODE

8 BIT MODE

DB0 = LSB

DB0/DB8 = LSB

DB15 = MSB

DB7/DB15 = MSB

When used in 8 BIT MODE the data bus must be

connected as follows:

DB0 TO DB8

DB4 TO DB12

DB1 TO DB9

DB5 TO DB13

DB2 TO DB10

DB6 TO DB14

DB3 TO DB11

DB7 TO DB15

DBCREQ

Dynamic Bus Control Request. If OPERATION Register bit i5 is

set LOW, this line will pulse LOW in response to a Valid

Dynamic Bus Control Mode Command, indicating

ACCEPTANCE of Bus Control Function.

Device Select. This signal must be low before the interface can

be selected for an I/O Read or Write function. The I/O Data Bus

will remain tri-stated, no operations will be executed when this

signal is high.

DONE

Low Pulse Indicates an I/O Operation has completed
