MC3501 FUNCTIONAL DESCRIPTION COMMANDS Commands determine the display mode and status of MC3501. A command is the first byte (b0 to b7) inputted to MC3501 via the DIN Pin after STB Pin has changed from “HIGH” to “LOW” State. If for some reason the STB Pin is set to “HIGH” while data or commands are being transmitted, the serial communication is initialized, and the data/commands being transmitted are considered invalid. COMMAND 1 : DISPLAY MODE SETTING COMMAND MC3501 provides 8 display mode settings as shown in the diagram below: As stated earlier a command is the first one byte (b0 to b7) transmitted to MC3501 via the DIN Pin when STB is “LOW”. However, for these commands, the bits 5 to 6 (b4 to b5) are ignored, bits 7 & 8 (b6 to b7) are given a value of “0”. The Display Mode Setting Commands determine the number of segments and grids to be used (1/8 to 1/16 duty, 24 segments). When these commands are executed, the display is forcibly turned off, the key scanning stops. A display command “ON” must be executed in order to resume display. If the same mode setting is selected, no command execution is take place, therefore, nothing happens. When Power is turned “ON”, the 16-digit, 24-segment modes is selected.
