Noise reduction circuits
(1) Reduced drivability for high-frequency oscillator circuit
(1) Reduced drivability for high-frequency oscillator circuit
(2) Reduced drivability for low-frequency oscillator circuit
(3) Single drive for high-frequency oscillator circuit
(4) Runaway prevention using SFR protection register
Noise reduction circuits are built in, allowing implementation of the following features.
These are set in EMCCR0 to EMCCR2 registers.
register. At reset, <DRVOSCH> is initialized to “1” and the oscillator starts oscillation
by normal-drivability when the power-supply is on.
(Purpose)
Reduces noise and power for oscillator when a resonator is used.
(Clock diagram)
(Setting method)
The drivability of the oscillator is reduced by writing”0” to EMCCR0<DRVOSCH>
