The PMP is a parallel 8-bit/16-bit input/output module
specifically designed to communicate with a wide
variety of parallel devices, such as communications
peripherals, LCDs, external memory devices, and
microcontrollers. Because the interface to parallel
peripherals varies significantly, the PMP module is
highly configurable.
