6.1
Responds to bus request for various kinds of MCU and translates to internal interface signals.
6.2
The control register stores register data to control the LCD panel. The register data is through the MCU Interface
read/write to control the register value. The read/write access of LUT is also controlled by the control register. The
detail of this register and register mapping will be discussed in Section 7 “Registers”.
6.3
Display output serializes the display data from display buffer and reconstructs the data according to the display
panel format. When the display mode is not 16 bpp, display data will be converted to color data by the built-in 18
bit LUT. For details about LUT, please refer to Section 15 “Look-Up Table Architecture”.
6.4
Display buffer consists of 256KB SRAM, which is organized as a 32-bit wide internal data path for fast display data
retrieval.
6.5
Provides programmable waveform for Pulse Width Modulation (PWM) and Contrast Voltage (CV) generation.
6.6
Clock Generator provides internal clocks. For detail operation of clock generator, please refer to Section 10.4.10
“Clocks”.
