input to X2 pin when an external oscillator is used
EMCCR0<EXTIN> register. X2 pin’s output is always “1”.
Reduces noise and power for oscillator when a resonator is used.
The drive ability of the oscillator is reduced by writing 0 to the
Remove the need for twin drives and prevent operational errors caused by noise
The oscillator is disabled and starts operation as buffer by writing “1” to
At reset, <EXTIN> is initialized to “0”.
