XC164 Servo testing with MATLAB GUI

Hello guys,

I want to generate a PulseWidthSignal with the CAPCOM2 or CAPCOM6 unit.
In addition i want to establish a connection with MATLAB. The goal is to send data from am MATLAB GUI to my XC164 Evalboard for testing a small servo drive. What interface do I have to use? COM / UART?
Im a newbie in µC programming the manuals are quite heavy to read.

Do you have any hints or a solution for me?
thx.

regards
