• Frame (Start: Addr7: Read: Ack: Data) or Frame (Start: Addr7: Write: Ack: Data)— The
oscilloscope triggers on a read or write frame in 7-bit addressing mode on
the 17th clock edge if all bits in the pattern match. For triggering purposes,
a restart is treated as a start condition.
• Frame (Start: Addr7: Read: Ack: Data: Ack: Data2) or Frame (Start: Addr7: Write: Ack:
Data: Ack: Data2)— The oscilloscope triggers on a read or write frame in 7-bit
addressing mode on the 26th clock edge if all bits in the pattern match. For
triggering purposes, a restart is treated as a start condition.
• 10-bit Write — The oscilloscope triggers on a 10-bit write frame on the 26th
clock edge if all bits in the pattern match. The frame is in the format:
Frame (Start: Address byte 1: Write: Address byte 2: Ack: Data)
For triggering purposes, a restart is treated as a start condition.
