Overview
MPC5606S Microcontroller Reference Manual, Rev. 7
66 Freescale Semiconductor
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
1.5.26 Liquid Crystal Display (LCD) driver
The LCD driver module has two configurations allowing a maximum of 160 or 228 LCD segments:
• As many as 40 frontplane drivers and four backplane drivers
• As many as 38 frontplane drivers and six 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
• On-chip generation of all output voltage levels
— LCD voltage reference taken from main 5 V supply
• LCD RAM – contains the data to be displayed on the LCD
— Data can be read from or written to the display RAM at any time
• End-of-frame interrupt:
— Optimize data refresh without visual artifacts
— Selectable number of frames between each interrupt
• Contrast adjustment using programmable internal voltage reference
• Remapping capability of four or six backplanes with frontplanes
— Increases pin selection flexibility
