ATSAMV71Q19B memory map

Where everything sits, at its exact address. The ATSAMV71Q19B has one 32-bit address space that its Arm Cortex-M7 core reaches flash, SRAM and the peripherals through alike: flash at 0x00400000, SRAM at 0x20400000, the peripherals from 0x40000000 and the core's own system registers (SysTick, the NVIC) at 0xE000E000.
