4 Triggering the Oscilloscope
•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 (Star t: Address byt e 1: Write: Addre ss byte 2: Ack:
Data)
For triggering purposes, a restart is treated as a start
condition.
