Operation Examples of Zero Suppression
Zero suppression operates when the display is 0, RBI is low, and the decimal
point is not lit. Then low is output to RBO.
Example 1: Zero suppression is not required and the RBI input and RBO
Example 2: Zeros are suppressed only for the digits on the left of the digit
Note: Use RBO output for the connection with RBI input only.
