Features
2.4.4 Parallel Data Interface (PDI)
The PDI is a digital interface used to receive external digital video or graphic content into the DCU.
The PDI input is directly injected into the DCU background plane FIFO. When the PDI is activated, all
the DCU synchronization is extracted from the external video stream to guarantee the synchronization of
the two video sources.
The PDI can be used to:
• Connect a video camera output directly to the PDI
• Connect a secondary display driver as slave with a minimum of extra cost
• Connect a device gathering various Video sources
• Provide flexibility to allow the DCU to be used in slave mode (external synchronization)
The PDI features the following:
• Supported color modes:
— 8-bit mono
— 8-bit color multiplexed
— RGB565
— 16-bit/18-bit RAW color
• Supported synchronization modes:
— Embedded ITU-R BT.656-4 (RGB565 mode 2)
— HSYNC, VSYNC
— Data Enable
• Direct interface with DCU background plane FIFO
• Synchronization generation for the DCU
2.4.5 Liquid Crystal Display (LCD) driver
The LCD driver module has two configurations allowing a maximum of 160 or 228 LCD segments:
• Up to 40 frontplane drivers and 4 backplane drivers
• Up to 38 frontplane drivers and 6 backplane drivers
Each segment is controlled and can be masked by a corresponding bit in the LCD RAM.
Four to six multiplex modes (1/1, 1/2, 1/3, 1/4, 1/5, 1/6 duty), and three bias (1/1, 1/2, 1/3) methods are
available. All frontplane and backplane pins can be multiplexed with other port functions.
The LCD driver module features the following:
• Programmable frame clock generator from different clock sources:
— System clock
— Internal RC oscillator
• Programmable bias voltage level selector
