Actually, the MSP430 *does* require that you program up the flash timing
generator in order ro correctly clock the flash state machine--it's just
you don't see it in the BSL.  The MSP430 bootstrap loader runs off the
MSP430's internal DCO at approximately 1MHz from reset so it can program
the FTG with a known oscillator frequency.  The key here is a *known
oscillator frequency*.
