Action Mode
1. Blank - Constant current segment drivers are off resulting in an all segments off condition.
Data D15 ~ D12 are 0. D11~D0 are not relevent in blank mode.
2. Normal (Operation) - Instructs device to display data loaded during previous steps. D11~ D0
are not relevent in the Normal Operation mode.
3. Load Register - Directs the device to recognize and load D11~ D0. In this mode D11 ~ D8
determines the specific register to be loaded (see figure 2) and D7 ~ D0 serves as the actual
data to be loaded for programming the brightness (duty cycle) or the particular digit.
4. All On - All constant current segment drivers are on resulting in an all segments illuminated
condition. D11 ~ D0 are not relevent in this mode.
5. Stand By - All display segments off condition. The Stand-By command turns off all internal
bias currents and serves as a low power consumption mode (<.2mA). Used with Stand-By set
up commands “All Data Clear” or “Data Not Cleared” (table 7).
The initial state, upon power up, is the BLANK state.
Application Note:
Stand-By and Blank perform similar functions in that the display is totally blank when either
command is input. Stand-By provides a low power consumption (<.2ma current draw on VDD)
mode by turning off all internal bias currents in the internal driver circuits. The Stand-By com-
mand also cuts off the Rext bias current used to regulate the programmed constant current
within the device.
