6.3 UART Trigger and Serial Decode

6.3.1 UART Setup

Setting the UART (Universal Asynchronous Receiver-Transmitter) signal includes two steps: configuring
the UART Trigger, and specifying the parameters of each input signal

RX

and

TX

.

Step 1.

Press the

then the

to enter the

Decode

menu.
