set as the TCNT0 compare-match signal simultaneously, a count-up clock cannot be
generated. Similarly, If the TMRY clock input is set as the TCNTX overflow signal and
the TMRX clock input is set as the TCNTY compare-match signal simultaneously, a
count-up clock cannot be generated. Simultaneous setting of these two conditions
should therefore be avoided.
