STMicroelectronics ST20450
The solution is to program the ShiftAmount for all banks with the same value. The compiler works around this by replacing each div and rem instruction with a code sequence which first chec ks the sign of the dividend and, if it is negative, flips the sign, performs the operation and then flips the sign of the result.| Part No. | ST20450 |
