Line 3: The '''Parallel Peripheral Interface''' ('''PPI''') is a peripheral found on the [[Blackfin]] embedded processor. The PPI is a [[half-duplex]], [[Two-way communication\|bi-directional]] port that is designed to connect directly to [[LCD]]s, [[CMOS sensor]]s, [[Charge-coupled device\|CCD]]s, video encoders (video [[Digital-to-analog converter\|DAC]]s), video decoders (video [[Analog-to-digital converter\|ADC]]s) or any generic high speed, parallel device. 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.
