27.0 PARALLEL MASTER PORT

(PMP)

Note 1: This data sheet summarizes the features

of the dsPIC33FJ32MC302/304,

dsPIC33FJ64MCX02/X04

and

dsPIC33FJ128MCX02/X04 family of

devices. It is not intended to be a

comprehensive reference source. To

complement 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

web

site

(www.microchip.com).

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 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 communication peripherals, LCDs, external

memory devices and microcontrollers. Because the

interface to parallel peripherals varies significantly,

the PMP is highly configurable.
