Parallel  Combine the sample data of the source channel waveforms 
as a parallel multi-channel bus and display the data as a 
single bus value 
RS232/UART  Display the input signal(s) of the TX source channel or/and 
RX source channel as bus 
I2C  Display the input signal of the SDA source channel as bus  
SPI  Display the input signal(s) of the MISO source channel 
or/and MOSI source channel as bus 
CAN  Display the input signal of the source channel (Rx, Tx, 
CAN_H, CAN_L or differential) as bus 
FlexRay  Display the input signal of the source channel (BP, BM or 
RX/TX) as bus
