PIC24FJ256GB110 FAMILY
19.0 PARALLEL MASTER PORT
(PMP)
The Parallel Master Port (PMP) module 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.
Key features of the PMP module include:
• Up to 16 Programmable Address Lines
• Up to 2 Chip Select Lines
• Programmable Strobe Options:
- Individual Read and Write Strobes or;
- Read/Write
Strobe with Enable Strobe
• Address Auto-Increment/Auto-Decrement
• Programmable Address/Data Multiplexing
• Programmable Polarity on Control Signals
• Legacy Parallel Slave Port Support
• Enhanced Parallel Slave Support:
- Address Support
- 4-Byte Deep Auto-Incrementing Buffer
• Programmable Wait States
• Selectable Input Voltage Levels
