MPY - Saturation Mode Overflow Test

The example illustrates a special case showing overflow. The addition result of 2 positive numbers may exceed the highest positive number (0x7FFF FFFF for 32 bit result) due to overflow indicating a negative result. By having the saturation mode enabled, this result can be truncated off to this highest positive number. Results with and without saturation mode are shown.

ACLK = 32.768kHz, MCLK = SMCLK = default DCO

Tested On: MSP430F5438A,MSP430FR5739,MSP430FR5969,MSP430FR2433
