no.
"no init" variables are not cleared or initialized by the C startup code
(a piece of code that is run before your "main" function).
it is useful e.g. to implement a clock. if you have a seconds counter
that is incremented by the timer. with a no init variable, the device
can be reset and it continues, after the reset, to count at the current
time instead of starting from zero. (in the case of a clock, the device
reset makes the clock to loose up to 1 second, so many resets make the
clock go behind but its still better than starting at zero)
