Restart — The oscilloscope will be triggered when another “Start” occurs before a “Stop".
No Ack — The oscilloscope will be triggered when the SDA line is high during any SCL’s ACK bit.
EEPROM
— The trigger searches for EEPROM control byte value
1010xxx on the SDA bus. And there is a Read bit and an ACK bit
behind EEPROM. Set the data value and compare type according to
Data1 and Limit Range . If EEPROM’s data is greater than (less
than, equal to) Data1 , the oscilloscope will be triggered at the edge
of the ACK bit behind the Data byte. The Data byte doesn’t need to
follow the EEPROM.
7 Address & Data — the oscilloscope will be triggered on the read or write frame in 7-bit address
mode.
Frame (Start: 7-bit address: R/W: Ack) — Data1 and Data2 are set to “0xXX”. If all bits match, then
trigger on the Ack bit followed by the R/W bit.
Frame (Start: 7-bit address: R/W: Ack: Data: Ack: Data2)—If all bits match, then trigger on the Ack bit
followed by the Data2.
