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/N/2). N is define by
CPUFS register. The low speed operation frequency (OSCL/2) comes from
RC oscillator was selected by mask option.
