19.0 PARALLEL MASTER PORT
(PMP)
Note 1: This data sheet summarizes the features
of the PIC32MX1XX/2XX family of
devices. It is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to Section 13. “Parallel
Master Port (PMP)” (DS61128) in the
“PIC32 Family Reference Manual”, which
is available from the Microchip web site
(www.microchip.com/PIC32).
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
The PMP is a parallel 8-bit input/output module
specifically designed to communicate with a wide
variety of parallel devices, such as communications
peripherals, LCDs, external memory devices and
microcontrollers. Because the interface to parallel
peripherals varies significantly, the PMP module 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
