C Serial Bus Interface
The I 2 C bus is a 2 wire interface with a serial data line (SDA) and
serial clock line (SCLK). The I 2 C protocol supports 7 or 10 bit
addressing and multiple masters. The decode software will trigger
on any of the following conditions: a start/stop condition, a restart,
a missing acknowledge message, Address, Data or Address& Data
frames. The I
2 C trigger can be configured for 7 or 10 bit addressing
with the option to ignore the R/W bit as well as triggering on a
data value or a specific address and direction (read or write or
both).
Panel operation 1. Insert each of the bus signals (SCLK, SDA) to
one of the oscilloscope channels.
