New to MSP432 and just have several questions: (Trying to build a very small board (so, minimal number of components) that support 18 channels of ADC. 1. Can I leave pins VSW / DCOR unconnected? What are they for? 2. I can use the internal oscillators. So, I do not really need to add external crystals, right? 3. The microcontroller can work with wide supply voltage range , 1.62-3.7. As a result, I do not really need regulator for battery-powered application. 4. The 24 ADC channels (MSP432P401RIPZ) are all 14 bit accuracy when used as single-ended. Correct? 5. For ADC, I can purely use the internal Vref rather than having to provide the Vref from outside. Correct? Thanks for your kind input!!
