The Demo outputs are 
multifunction outputs that can be 
configured for probe 
compensation, as a trigger output 
or as a basic waveform generator 
for demonstration purposes. (FM 
signal, UART, I
2
C, SPI). 
By default, the 3 Demo outputs are 
configured as: 
1: Trigger output 
2: FM waveform 
3: Probe Compensation signal  
CAL (Demo 3) outputs a 2Vp-p, 
square wave signal for probe 
compensation. 
Please see page 171 for details. 
The Logic Analyzer port is used to 
connect to a Logic Analyzer probe. 
This port only functions if the 
optional logic analyzer module is 
installed.
