Provides control over the device's debug interface selection. This class is for advanced use only. The recommend method to control the debug interface is through the MODE pin. Take care to track the interface used and whether or not it affects TinyBooter because these settings can only be undone by reflashing the firmware.
When the MODE pin is in its default state, the interface set in this class will be used. If MODE is set to the opposite state, the debug interface that is not selected will be used. In either case, when the serial interface is to be used, the COM port set in this class will be used. This class does not affect the GHI bootloader.

Provides access to Runtime Loadable Procedures (RLP). RLP allows developers to load and execute their own compiled C or Assembly functions at
runtime. RLP supports loading ELF executables and, for advanced users, loading binary images using the GHI.LowLevel.AddressSpace class. The
user can load multiple images in the reserved RLP memory region. Compiled functions are executed natively and can perform much faster than
managed application. This is very useful for calculation intensive applications. RLP also has extensions that can be used directly from native
code. You can use dynamic memory allocation, perform native tasks at a specific time, install interrupts, and more. See
https://www.ghielectronics.com/docs/50/ for more information.
