Digit- and Control-Registers

The AS1116 devices contain 8 Digit-Registers,11 control-registers and 8 diagnostic-registers, which are listed in Table 7. All registers are

selected using a 8-bit address word, and communication is done via the serial interface.

Digit Registers – These registers are realized with an on-chip 64-bit memory. Each digit can be controlled directly without rewriting the

whole register contents.

Control Registers – These registers consist of decode mode, display intensity, number of scanned digits, shutdown, display test and fea-

tures selection registers.

Note: Write operation: D14=0; Read operation: D14=1.
