1.12.17 (PMP)
The Parallel Master Port (PMP) is a parallel 8-bit/16-bit I/O module specifically designed to communicate with a wide variety of parallel devices such as communications peripherals, LCDs, external memory devices and micro-controllers. Because the interfaces to parallel peripherals vary significantly, the PMP module is highly configurable.
