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 communication 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:
- Main and Secondary Operating modes
- 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
- Address Auto-Increment/Auto-Decrement
- Programmable Address/Data Multiplexing
- Programmable Polarity on Control Signals
- Legacy Parallel Port Support
- Enhanced Parallel Support:
- Address support
- Four bytes deep, auto-incrementing buffer
- Schmitt Trigger or TTL Input Buffers
- Programmable Wait States
- Dual Buffer Mode with Separate Read and Write Registers
- Read Initiate Control
