“t
cp
” represents one cycle time of the machine clock.
Oscillation time of oscillator is time that amplitude reached the 90
%
. In the crystal oscillator, the oscillation time is
between several ms to tens of ms. In FAR/ceramic oscillator, the oscillation time is between handreds of
μ
s to
several ms. In the external clock, the oscillation time is 0 ns.
Any reset can not fully initialize the Flash Memory if it is performing the automatic algorithm.
