9.5 Using Logic Channels in Buses
You can use logic channels as input sources of various buses. Parallel buses are dedi-
cated for analysis of logic channels. Serial buses accept analog and digital channels as
input.
The general usage of buses is described in the following chapters:
●
Chapter 11.1, "Bus Configuration", on page 120
●
Chapter 11.2, "Bus Table: Decode Results", on page 122
