USS SW Library best practices

1. Avoid accessing gUSSLEATempMemBlock until USS_startUltrasonicMeasurement and USS_startLowPowerUltrasonicCapture return control to the application
   • In order to avoid unexpected Non-maskable Interrupts during USS_startUltrasonicMeasurement or USS_startLowPowerUltrasonicCapture, the application must ensure CPU or DMA does not attempt to access gUSSLEATempMemBlock buffer until the API retunr control to the application. For more information please refer to the MSP430FR58xx, MSP430FR59xx, and MSP430FR6xx Users Guide section “Data Transfer Controller (DTC) and Internal Data Buffer”
