Parallel Master Port
Abstract
The parallel master port allows the PIC32 to communicate with certain devices with a parallel port. This chapter describes the special function registers (SFRs) that control the parallel master port, with sample code for printing to an LCD screen.

The parallel master port (PMP) uses multiple wires to communicate multiple bits simultaneously (in parallel). This is in contrast to serial communication, where one bit is sent at a time. Parallel ports were once popular on computers and printers, but they have now been displaced by newer communication technologies, such as USB and Ethernet. Nevertheless, the PMP provides a simple interface to some devices, such ...
