13.1 INTRODUCTION
The Parallel Master Port (PMP) is a parallel 8-bit/16-bit I/O module specifically designed to
communicate with a wide variety of parallel devices such as communications peripherals, LCDs,
external memory devices and microcontrollers. Because the interfaces to parallel peripherals
vary significantly, the PMP module is highly configurable. The key features of the PMP module
include:
Up to 24 programmable address lines
Up to two Chip Select lines with two alternate Chip Selects for extended addressing
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 bytes deep, auto-incrementing buffer
Schmitt Trigger or TTL input buffers
Programmable Wait states
Freeze option for in-circuit debugging
Separate configurable read/write registers or dual buffers for Master mode (not available on
all devices)
