Only one overflow is allowed for this function to work e.g. if depth = 100, you must not
write more than 2*depth-1 items in one rush without updating write pointer. Otherwise
write pointer wraps and you pointer states are messed up. This can only happen if you
use DMAs, write functions do not allow such an error. Avoid such nasty things!
All reading functions (read, peek) check for overflows and correct read pointer on their own such
