Difference between isolated and memory mapped
WebMay 27, 2015 · Port mapping is to assign which port to use. For example, which port you want to use for serial communication, UART1 or UART2 or USB? Memory mapped IO shares same memory address space for IO (same space but unique address). But, Memory isolated IO has separated space for memory & IO. *gpio_for_led = 1; // mem … WebJun 8, 2024 · Isolated I/O. Memory Mapped I/O. Memory and I/O have separate address space.
