26 I2C Triggering and Protocol Decode
• Address with no Ack — Finds when the acknowledge of the selected address
field is false. The R/W bit is ignored.
• Missing Acknowledge — Finds SDA data is high during any Ack SCL clock bit.
• EEPROM Data Read — Finds EEPROM control byte value 1010xxx on the SDA
line, followed by a Read bit and an Ack bit. It then looks for the data value
and qualifier set by the Data is and the Data controls.
• Frame(Start:Address7:Read:Ack:Data) — Finds a read frame on the 17th clock
edge if all bits in the pattern match.
• Frame(Start:Address7:Write:Ack:Data) — Finds a write frame on the 17th clock
edge if all bits in the pattern match.
• Frame(Start:Address7:Read:Ack:Data:Ack:Data2) — Finds a read frame on the
26th clock edge if all bits in the pattern match.
• Frame(Start:Address7:Write:Ack:Data:Ack:Data2) — Finds a write frame on the
26th clock edge if all bits in the pattern match.
