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.

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”. MSB 0 LSB 1 0 0 b3 b2 b1 b0 Data Write Mode Settings: 00 : Write Data to Display Mode Address Increment Mode Settings (Display Mode ) : 0 : Increment Address after Data has been Written 1 : Fixes Address Mode Settings : 0 : Normal Operation Mode 1 : Test Mode 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.
