9.6MHz, inspection of the TC0 overflow (OVF) flag is used to expand the timer by 8 bits, providing a 16-bit timer. The OVF flag is inspected once every half-cycle (of the C- clock), which is sufficiently often to ensure that all TC0 OVF are detected. In relation to the range of the 16-bit timer implemented
