Bit6 ~ 4 : Normal register bits.
ECKIN : External Clock Input Enable Bit.
0 = Disable oscillator external clock input
1 = Enable oscillator external clock input (must be set in external oscillator of RC mode )
OSO2E : Both of Internal and external oscillator Enable Bit.
0 = Only use internal oscillator or external oscillator
1 = Internal and external (LF mode only) oscillator enable both
OSC2O : OSC2/PA4 Oscillator Clock Output Enable Bit.
0 = Disable OSC2/PA4 oscillator clock output in internal or external of RC mode oscillator
1 = Enable OSC2/PA4 oscillator clock output in internal or external of RC mode oscillator
OSCIN : MCU Internal Or external oscillator Select Bit.
0 = Default the MCU clock based on internal 4MHz oscillator
1 = The MCU clock based on external oscillator (type from option select),
When internal 4MHz oscillator change to external oscillator must wait OST time 20ms.
Example : change oscillator on external oscillator (oscillator type from option select)
