FUNCTIONAL DESCRIPTION
COMMANDS
A command is the first byte (b0 to b7) inputted to IK6207TQ-ER via DIN, DI/O Pin after STB Pin has
changed From ”HIGH” to “LOW” state. If for some reason the STB Pin is set “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 COMMANDS
IK6207TQ-ER provides 4 display mode setting as shown in the diagram below: As stated earlier a command
is the first one byte(b0 to b7) transmitted to IK6207TQ-ER via the DIN, DI/O Pin when STB is “LOW”.
However, for these commands, Bit 3 & Bit 8 (b2 to b7) are given a value of “0”.
The Display Mode Setting Commands determine the number of segments and grids be used (14 to 9
segments, 4 to 7 grids). 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 mode 11 is selected.

COMMAND 2: DATA SETTING COMMANDS
The Data Setting Commands executes the Data Write Mode for IK6207TQ-ER. The Data Setting Command,
the bits5 and 6 (b4, b5) are given the value of “0”. , bit7 (b6) is given the value of “1” while bit8 (b7) is given
the value of “0”. Please refer to the diagram below. When power is turned ON, bit 4 to bit 1 (b3 to b0) are
given the value of “0”.

COMMAND 3: ADDRESS SETTING COMMANDS
Address Setting Commands are used to set the address of the display memory. The address is considered
valid if it has a value of “00H” to 0DH”. If the address is set to 0EH or higher, the data is ignored until a valid
address is set. When power is turned ON, the address is set at “00H”.Please refer to the diagram below.
