“Shifting display digits”. When the upper 1 bit (B7) of the 1
command data, and stored in the “Command register 1”. The contents of the “Command register 1” are initialized to
the default values by the power-ON reset or the reset signal, as shown below.
The “Command register 1” is used for setting “Duty ratio for timing signal”, “Display control ON/OFF” and
DEFAULT VALUES OF COMMAND REGISTER 1
The output waveforms of timing signal are shown in “
When the “Display control OFF” is set, segment drivers output waveforms but all timing signal outputs are halted
