AS1116
Datasheet - Detailed Description
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.
