function. In other words, it indicates when LCD is initialized and GUI of system is displayed on the LCD.
CAMERA
DSP provides clock to operate sensor and controls internal register of sensor through the I2C master embedded
in DSP to make sensor operate normally. After completion of internal register setting, sensor supplies YUV422
image data, synchronous signal and pixel clock synchronized with pixel of image data to DSP. VSYNC is a
synchronized signal to differentiate frames and HREF is a synchronized signal to differentiate lines. These
signals are synchronized with the pixel clock. Input image data through the sensorinterface is previewed on the
LCD up to 30fps through the IMAGE ENHANCER.
EXTERNAL CODEC
Normally codec bypass signal from MSM6500 to Speaker, Receiver or Headset. However, when we listen to the
music in "My Music" folder codec performs 3-D sound enhancement and automatic level control for
microphone or line input. The on-chip ADC and DAC are of a high quality using a multi-bit, low-order
oversampling architecture to deliver optimum performance with low power consumption. It supports I2S audio
data format between DSP and codec.
