Hi Expert,

    Strong,

    I believe this is referring to the address range vs the word size.  You are correct that the min word size is 16 data bits on the C28x.

    So, for HWBIST to work correctly the stack pointer(SP in the CPU register) must reside between 0x0020-0xFFAF(taking into account the 1st 32 words reserved and the 80 words needed for full context save).

    Best,

    Matthew
