Help¶

When this option is true, the k_ticks_t values passed to kernel APIs will be a 64 bit quantity, allowing the use of larger values (and higher precision tick rates) without fear of overflowing the 32 bit word. This feature also gates the availability of absolute timeout values (which require the extra precision).
