Although an MSP-FET can interact with the MSP-BSL to carry out firmware updates, does the MSP-FET depend on the MSP-BSL to carry out firmware loading and debugging work? In other words, when using CCS to load firmware into an MSP430, and when using CCS to step through our firmware program to test and debug it, does the MSP-FET depend on the MSP-BSL to load, test, and debug our program?
