5.5.3 Reducing the Oscillator Driving Capability
This function is intended for restricting oscillation noise generated from the oscillator and
reducing the power consumption of the oscillator when it is connected to the oscillator
connection pin.
Setting the SYSCR2<DRVOSCH> to "1" reduces the driving capability of the high-speed
oscillator. (low capability).
This is reset to the default setting "0." When the power is turned on, oscillation starts with
the normal driving capability (high capability). This is automatically set to the high driving
capability state (<DRVOSCH> ="0") whenever the oscillator starts oscillation due to mode
transition.
