Overview

Overview
The PPI is a half-duplex, bidirectional port accommodating up to 16 bits
of data. It has a dedicated clock pin and three multiplexed frame sync
pins. The highest system throughput is achieved with 8-bit data, since two
8-bit data samples can be packed as a single 16-bit word. In such a case,
the earlier sample is placed in the 8 least significant bits (LSBs).

Features

The PPI includes these features:
• Half duplex, bidirectional parallel port
• Supports up to 16 bits of data
• Programmable clock and frame sync polarities
• ITU-R 656 support
• Interrupt generation on overflow and underrun
Typical peripheral devices that can be interfaced to the PPI port:
• A/D converters
• D/A converters
• LCD panels
• CMOS sensors
• Video encoders
• Video decoders
