Table IV. Basic Control Strobe Functions
RESET CS WE RE UPD Function
0XXXXGlobal Reset. Disables all outputs and resets all output current to code 0111 (16 mA).
11XXX Disable All Control Signals. Signal matrix/currents remain the same. D5:D0 are high impedance.
1001XWrite Enable. Write D5:D0 data into first rank register addressed by A6:A0.
10X0X Single-Output Readback. Second rank register data for output A6:A0 appears on D5:D0.
10XX0
Global Update. Copy all first rank data into second rank registers.
10010 Transparent Write and Update. D5:D0 immediately control programming. Use RE as gating signal.
