MPY - Saturation Mpode Underflow Test

Description: The example illustrates a special case showing underflow. Underflow occurs when adding 2 negative numbers yields a positive result. By having the saturation mode enabled, the result if rounded off to the highest negative number (0x8000.0000 for 16 bit). Results can be viewed in the debugger window.

ACLK = 32.768kHz, MCLK = SMCLK = default DCO

Tested On: MSP430F5438A,MSP430FR5739,MSP430FR5969,MSP430FR2433
