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 … WebFinally, with the a future update, two additional options will be made available in-game in a new 64-bit option menu: Memory Map Input/Output (Default: Off): When enabled, this will allocate additional memory to MapleStory in order to improve data access speeds, improving overall performance.
