The oscillation stabilization time refers to the time interval that is required for the oscillation to get stabilized after the
following reference timing points: (See Figure 4)
VDD goes above the operating voltage lower limit.
An instruction for starting the OSC1 clock oscillator circuit is executed.
Oscillation starts after the microcontroller exits the X'tal HOLD mode with the ENOSC1 bit (OCR0 register, bit 1)
set to 1.

The oscillation stabilization time refers to the time interval that is required for the oscillation to get stabilized after the
instruction for starting the OSC0 clock oscillation circuit is executed. (See Figure 4)
Note: The components that are involved in oscillation should be placed as close to the IC and to one another as possible
because they are vulnerable to the influences of the circuit pattern.
