The MSP430F47xxx has 4 16-bit hardware multiplier result registers named RES0 to RES3. I have been tring to access these using a pre-defined pointer to make my code more readable. I have tried to use the construct:
unsigned
long long * const pHwMultResult = (unsigned long long*) & RES0; // A pointer to the (low) result register type cast to 64-bits
However I cannot access the registers values or assign them using the pointer I created even though I do see that the pointer points to the right spot (and some values are there). Looking at *(pHwMultiResult) in the variable display always shows 0 even though there are some values in RES0 - RES 3.
Statements such as:
gRawRecDose.
SumSq = *pHwMultResult; // Return Result to the global accumulating variable
Do not work. In addition I have noticed that structure members with unsigned long long or long long types cannot be assigned values in my code. I do not know why this is.
