WebARM peripherals. A peripheral device performs input and output functions for the chip by connecting to other devices or sensors that are off-chip. All ARM peripherals are memory mapped-the programming interface is a set of memory- addressed registers. The address of these registers is an offset from a specific peripheral base address. WebApr 28, 2024 · The Pi 2 and 3 have 1024MB of memory from 0x00000000 to 0x3FFFFFFF, so you'd expect the IO base to be at 0x40000000 - but that memory range is not available, so the IO address was set to 0x3F000000 instead and the last 1MB of memory was sacrificed to allow the IO to work (so they really only have 1023MB of memory available).
