There are two primary clock generators: a low-power ring oscillator (LP_OSC) and a
crystal oscillator. See
LP_OSC is the source for the BASE_PCR_CLK that clocks the CGU itself and for
BASE_SAFE_CLK that clocks a minimum of other logic in the device (like the watchdog
timer). To prevent the device from losing its clock source LP_OSC cannot be put into
power-down. The crystal oscillator can be used as source for high-frequency clocks or as
an external clock input if a crystal is not connected.
Secondary clock generators are a PLL and seven fractional dividers (FDIV0:6). The PLL
has three clock outputs: normal, 120 phase-shifted and 240 phase-shifted.
