26.0 PARALLEL MASTER PORT
(PMP)
Note 1: This data sheet summarizes the features
of the dsPIC33FJ32GP302/304,
dsPIC33FJ64GPX02/X04,
and
dsPIC33FJ128GPX02/X04 families of
devices. It is not intended to be a compre-
hensive reference source. To comple-
ment the information in this data sheet,
refer to “Section 35. Parallel Master
Port (PMP)” (DS70299) of the
“dsPIC33F/PIC24H Family Reference
Manual”, which is available from the
Microchip website (www.microchip.com).
2: Some registers and associated bits
described in this section may not be avail-
able on all devices. Refer to Section 4.0
“Memory Organization” in this data
sheet for device-specific register and bit
information.
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.
Key features of the PMP module include:
• Fully multiplexed address/data mode
• Demultiplexed or partially multiplexed address/
data mode
- up to 11 address lines with single chip select
- up to 12 address lines without chip select
• One Chip Select Line
• 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
