"AND" or “Or” combination of channels. Each channel can have a value of high (1), low
(0) or don't care (X). A rising, falling edge, rising or falling can be specified for one
channel included in the pattern. When an edge is specified, the oscilloscope will trigger
at the edge specified if the pattern set for the other channels are true (namely the
actual pattern of the channel is the same with the preset pattern). If no edge is
specified, the oscilloscope will trigger on the last edge that makes the pattern true. If all
the channels in the pattern are set to "Don’t Care", the oscilloscope will not trigger.
