Web13 sep. 2024 · The memory map, as it is often called, is essentially the bridge between the hardware and software projects – the hardware team allocating each of the various memory and peripheral devices their own chunk of the processor's address space, the software team then writing their code to access the memory and peripherals at the given locations. WebL2 memory can be configured as mapped memory, cache, or combinations of the two. The peripheral set includes: two configurable video ports; a 10/100 ... three UARTs with hardware handshaking support on one UART; three pulse width modulator (PWM) peripherals; and two external memory interfaces: an asynchronous external memory ...
