When used as a gate input, the counter only counts while the active level specified by the MOD0 bit of the
control register is input to the TINn pin. In this case, the count clock continues to operate unless stopped. The
software trigger can be used in gate mode, regardless of the gate level. Input a pulse width of at least 2T +
200ns to the TINn pin. Figure 15.3-3 "Gate input operation of 16-bit Reload Timer" shows the operation of
gate input.
