Signal Description
6 MHz Master Clock.
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 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.
Same as DATA CHA, except for Channel B. (BUS 1).
Same as DATA CHA, except for Channel B. (BUS 1).
I/O DATA BUS. Data Bus for all SUBSYSTEM
READ and WRITE OPERATIONS.
16 BIT MODE
8 BIT MODE
DB0 = LSB
DB15 = MSB
DB0/DB8 = LSB
DB7/DB15 = MSB
When used in 8 BIT MODE the data bus must be
connected as follows:
DB0 TO DB8
DB1 TO DB9
DB2 TO DB10
DB3 TO DB11
DB4 TO DB12
DB5 TO DB13
DB6 TO DB14
DB7 TO DB15
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.
Low Pulse Indicates an I/O Operation has completed
