PIC18F87J11 FAMILY
11.0 PARALLEL MASTER PORT
The Parallel Master Port module (PMP) is a parallel,
8-bit I/O module, specifically designed to communicate
with a wide variety of parallel devices, such as commu-
nication peripherals, LCDs, external memory devices
and microcontrollers. Because the interface to parallel
peripherals varies significantly, the PMP is highly
configurable. The PMP module can be configured to
serve as either a Parallel Master Port or as a Parallel
Slave Port.
