Clocks
The clock generation circuitry is part of the System Controller. It generates the
main system clock HCLK, that is supplied to most modules. It is also used to set
up and generate the pixel clocks VO0CLK and VO1CLK for the Video Output
modules.
Another important task of the System Controller is the generation of internal reset
signals.
