Microchip Technology 

PIC32MX1XX/2XX/5XX 64/100-PIN FAMILY

20.0 PARALLEL MASTER PORT

(PMP)

Note:

This data sheet summarizes the features

of the PIC32MX1XX/2XX/5XX 64/100-pin

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)” (DS60001128) in

the “PIC32 Family Reference Manual”,

which is available from the Microchip

web site (www.microchip.com/PIC32).

The PMP is a parallel 8-bit or 16-bit input/output mod-

ule 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.

The following are the key features of the PMP module:

• 8-bit,16-bit interface

• Up to 16 programmable address lines

• Up to two Chip Select lines

• Programmable strobe options:

- Individual read and write strobes, or

- Read/write strobe with enable strobe

- Selectable polarity

• Address auto-increment/auto-decrement

• Programmable address/data multiplexing

• Programmable polarity on control signals

• Parallel Slave Port support:

- Legacy addressable

- Address support

• Read and Write 4-byte deep auto-incrementing buffer

• Programmable Wait states

• Operate during CPU Sleep and Idle modes

• Fast bit manipulation using CLR, SET and INV

registers

• Freeze option for in-circuit debugging

Note: On 64-pin devices, data pins PMD<15:8>

are not available in 16-bit Master modes.
