Resolved! STM32L0 -> DMA, parallel operations

Dumb question, can the DMA perform separate, parallel operations with the different channels? For example, could I use the DMA to transmit with the UART and the SPI devices at the same time without one interrupting the other? I'm unclear from readin...

What is the Stm32L4 VDD12

"Hello, while examining the STM32L412C8 microcontroller, I came across the term VDD12. What is VDD12, and can I use the peripherals without making the VDD12 connection? In other words, is it mandatory to make the VDD12 connection?"
