Column Description
R/W bit Value of the R/W bit
Ack bit Value of the address acknowledge bit
Values Value of all data bytes of the frame. The data format
is selected below the table.
Example:
The signal in figure 10-4 shows a write access followed by a read access, both with 10bit
address. The decoded data shows a No Ack bit at the end of the read data. This No Ack
bit is sent according to the protocol definition and is not an error. Thus, the decode results
in the table indicate "Ack" for the second frame.

C Translation Table (Option R&S RTO-K1)
Translation tables are protocol-specific. An I

C protocol translation file contains three
values for each bus node. After a file was loaded, these values are shown in the trans-
lation table:
"ID Type": address type, 7-bit or 10-bit long
