Function
0
X
Global Reset. Reset all second rank enable bits to zero (disable all outputs).
1
X
Control Disable. Ignore all logic (but the signal matrix still functions as programmed). D [6:0]
are high impedance.
1
0
1
Single Output Preprogram. Write input configuration data from Data Bus D [6:0] into first rank
of latches for the output selected by the Output Address Bus A [4:0].
1
0
1
0
1
Single Output Readback. Readback input configuration data from second rank of latches onto
Data Bus D [6:0] for the single output selected by the Output Address Bus A [4:0].
1
0
1
0
Global Update. Copy input configuration data from all 17 first rank latches into second rank of
latches, updating signal matrix connections for all outputs.
1
0
1
0
Transparent Write and Update. It is possible to write data directly onto rank two. This simplifies
logic when synchronous signal matrix updating is not necessary.
1 X means don’t care.

Upper Address/Data Range. Connect Output 16
(A[4:0] = 10000) to Input 32 (D[5:0] = 100000).
Binary Output Number 2
1
Binary Input Number
Enable Output. Connect Selected Output (A[4:0] = 0 to 16) to
Designated Input (D[5:0] = 0 to 32) and Enable Output
(D6 = 1).
Binary Output Number2
0
X
Disable Output. Disable Specified Output (D6 = 0).

Binary Input Number
Broadcast Connection. Connect all 17 outputs to same
designated input and set all 17 enable bits to D6. Readback is
not possible with the broadcast address.
