|
The iProc clock controller manages clocks that are common to the iProc family.
|
|
An SoC from the iProc family may have several PLLs, e.g., ARMPLL, GENPLL,
|
|
LCPLL0, MIPIPLL, and etc., all derived from an onboard crystal. Each PLL
|
|
comprises of several leaf clocks
|
|
|
|
ASIU clocks are a special case. These clocks are derived directly from the
|
|
reference clock of the onboard crystal.
