10-bit addressing
The 10-bit addressing and 7-bit addressing of the IIC bus are compatible, so that de-
vices with 7-bit address and 10-bit address mode can be used on the same bus at the
same time. When transmitting 10-bit addresses, the first byte is a special reserved ad-
dress. To indicate that the 10-bit address is currently being transmitted.

Start condition
Stop condition
The IIC (Inter-Integrated Circuit Bus) signal settings include a serial data (SDA) line and
a serial clock (SCL) line connected to an oscilloscope, and then specify the input signal
threshold voltage level.
Press the front panel Trig Menu button to open the trigger function menu.
[Type] Select IIC and press V0 to confirm.
[Address width] Select 7 or 10 digits.
[Clock Source] Select CH1～CH4 or LA as the trigger source.
Note: LA must be inserted when LA is used as trigger source
[Data source] Select CH1～CH4 or LA as the trigger source.
Note: LA must be inserted when LA is used as trigger source
[When] Set IIC trigger conditions:
Start bit: IIC start condition detected
Stop bit: IIC stop condition detected
No response: trigger when IIC bus response level error
Address: IIC address is received, trigger when the data is equal to the user set value
Restart: triggered when a new start condition occurs before the stop condition
Address and data: Triggered when the IIC address is received and the data (4 bytes of
data) is equal to the user set value.
[Address] Identifier data when IIC is triggered.
[Data 1] Data when IIC is triggered
[Data 2] Data when IIC is triggered
[Data 3] Data when IIC is triggered
[Data 4] Data when IIC is triggered
