Acquire the Signal
5. For I2C , push Include R/W in Address and
then push the desired side-bezel button for Yes
or No.
This control determines how the oscilloscope
shows the I
2
C addresses in bus decode traces,
cursor readouts, Event Table listings, and
trigger settings.
If you select Yes, then 7-bit addresses are
displayed as eight bits, where the eighth bit
(LSB) is the R/~W bit.
10-bit addresses are displayed as 11 bits. The
fi rst two bits are the two MSBs of the address.
The next bit is the R/~W bit. The last eight
bits are the eight LSBs of the address. (In the
physical layer of the I
2
C protocol, 10 bit I
2
C
addresses are preceded by the fi ve bit code,
11110. The oscilloscope never includes these
fi ve bits in address readouts.)
If you select No, then 7-bit addresses are
displayed as seven bits and 10-bit addresses
are displayed as ten bits.
