If you want to modify the frequency of audio output, you have to modify the register value at
register 0x15 (reference ADV7513_Programming_Guide_R0.pdf). I2S Standard uses MSB to LSB
serial way of transmitting. The demo uses sinusoid signal to make sound from a reference of look
up table created by calculated sinusoid wave data.
 Video Pattern Generator
The module "Video Pattern Generator" copes with generating video patterns to be presented on the
LCD monitor. The pattern is composed in the way of 24-bit RGB 4:4:4 (RGB888 per color pixel
without sub-sampling) color encoding, which corresponding to the parallel encoding format defined
in Table 5-2 of the "ADV7513 Hardware User's Guide," as shown below.
