Figure 13-2: 10-bit address, write access
A 10-bit address for read access requires 3 bytes. The first 2 bytes are identical to the
write access address. The third byte repeats the address bits of the first byte and sets
the read bit.

Trigger
The R&S
RTO6 can trigger on various parts of I²C messages. The data and clock lines
must be connected to the input channels, triggering on math and reference waveforms
is not possible.
You can trigger on:
●
Start or stop condition
●
Repeated start condition
●
Transfer direction (read or write)
●
Bytes with missing acknowledge bit
●
Specific slave address or address range
●
Specific data pattern in the message
