§ System function description:
S-1: System Oscillator
The high-speed oscillator is operated in built-in RC mode. Built-in RC
oscillator is fixed 4MHz
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 12 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. In the normal operation, the system clock comes from
high-speed system oscillator (OSCH/2). The low speed operation frequency
(OSCL/2) comes from RC oscillator.
