Some trigger types have additional settings that can be defined. In this case, the "Edit"
button appears next to "Type" the function. Open it for a detailed definition of the trig-
ger conditions.
"Start bit"
Triggers on a start bit. The start bit is the first low bit after a stop bit.
"Packet start"
Triggers on the begin of a data packet.
"Data"
Trigger on a serial pattern at a defined position in the data packet.
The pattern can include several subsequent symbols (data frames).
"Parity error"
Triggers on a parity error indicating a transmission error. This trigger
type is only available if a parity is configured for the UART bus.
"Break condi-
tion"
Triggers if a start bit is not followed by a stop bit, the data line
remains at logic 0 for longer than a UART word.
"Stop error"
Triggers if the stop bit is a logic 0.
