PIC32MZ Embedded Connectivity with Floating Point Unit (EF) Family
23.0 PARALLEL MASTER PORT
(PMP)
The PMP is a parallel 8-bit/16-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:
• 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
• Address auto-increment/auto-decrement
• Programmable address/data multiplexing
• Programmable polarity on control signals
• Parallel Slave Port support:
- Legacy addressable
- Address support
- 4-byte deep auto-incrementing buffer
• Programmable Wait states
• Operate during Sleep and Idle modes
• Fast bit manipulation using CLR, SET, and INV
registers
