Example commands:
MATLAB/CCS:
– regwrite - Write a value to a specified register on the target
processor
– write - Write data to memory on the target processor
– get - Return the property values for a link to CCS
– MATLAB/RTDX:
– enable - Enable the RTDX interface, a specified channel, or all
RTDX channels
– readmat - Read a matrix of data from specified RTDX channels
