The Parallel Master Port (PMP) module is a parallel
8-bit I/O module, specifically designed to communi-
cate with a wide variety of parallel devices, such as
communication peripherals, LCDs, external memory
devices and microcontrollers. Because the interface
to parallel peripherals varies significantly, the PMP is
highly configurable.
