§ System function description:  
S-1: System Oscillator  
The high speed oscillator is operated in built-in RC mode. It is fixed  
4MHz (typical at VDD=5V).  
S-2: Peripheral Oscillator  
The low speed oscillator was built-in an internal RC oscillator that is for  
low power consumption consideration and fixed peripheral device timing  
control. Built-in RC oscillator and the frequency range between 11 KHz~21  
KHz.  
S-3: CPU clock  
The CPU clock comes from system/peripheral oscillator which was  
controlled by H/L bit in PS register. The high speed operation frequency  
comes from system oscillator. The low speed operation frequency comes  
from peripheral oscillator.
