Clock Generator
The Clock Generator embeds one low-power RC Oscillator, one Main Oscillator and one PLL
with the following characteristics:
RC Oscillator ranges between 22 KHz and 42 KHz
Main Oscillator frequency ranges between 3 and 20 MHz
Main Oscillator can be bypassed
PLL output ranges between 80 and 200 MHz
It provides SLCK, MAINCK and PLLCK.
