When the nextTick calculated will overflow the 16-bit unsigned int, it will start from 0.
If the timer has not yet overflown in the next check, then the check will return true before the logic distance in ticks was reached yet.

Solution:

Check if the difference between timer and nextTick is more than (half?) of the timer-overflow

if(timer >= nextTick && (timer - nextTick) < (2^timerBits /2))

Solution: - Check if the difference between <code>timer</code> and <code>nextTick</code> is more than (half?) of the timer-overflow <br><br> <code>if(timer >= nextTick && (timer - nextTick) < (2^timerBits /2))</code>
