Noise Reduction Circuits
(1) Reduced drivability for high-frequency oscillator
(2) Reduced drivability for low-frequency oscillator
(3) Single drive for high-frequency oscillator
(4) SFR protection of register contents
(5) ROM protection of register contents
to EMCCR3 registers.
(1) Reduced drivability for high-frequency oscillator
Noise reduction circuits are built in, allowing implementation of the following features.
The above functions are performed by making the appropriate settings in the EMCCR0
(Purpose)
(Block diagram)
(Setting method)
EMCCR0<DRVOSCH> register. By reset, <DRVOSCH> is initialized to 1 and the
oscillator starts oscillation by normal-drivability when the power-supply is on.
When VCC=2V±10%, don’t set EMCCR0<DRVOSCH> to "0".
Reduces noise and power for oscillator when a resonator is used.
