WebMemory-mapped I/O is suitable for devices which must move large quantities of data quickly, such as graphics cards. Memory-mapped I/O can be used either instead of or more often in combination with traditional registers. For example, graphics cards still use registers for control information such as setting the video mode. WebThe Data Latch register (LATD) is also memory mapped. Read-modify-write operations on the LATD register read and write the latched output value for PORTD. All pins on PORTD are implemented with Schmitt Trigger input buffers. Each pin is individually configurable as an input or output. Three of the PORTD pins are multiplexed with outputs P1A, P1B, P1C and …
