Engineering:Parallel Peripheral Interface

From HandWiki

The Parallel Peripheral Interface (PPI) is a peripheral found on the Blackfin embedded processor. The PPI is a half-duplex, bi-directional port that is designed to connect directly to LCDs, CMOS sensors, CCDs, video encoders (video DACs), video decoders (video ADCs) or any generic high speed, parallel device.[1]

The width of the PPI is programmable and can be set between 8 and 16 bits in 1-bit increments. The latest Blackfin family (BF54x) also features an 18/24-bit PPI for direct connection to RGB LCD panels.

The PPI can run from 0 MHz up to 66 MHz.

The PPI has a dedicated clock pin, three multiplexed frame sync pins, and between 16 and 24 data pins.[2]
