with the counter. In this interval, therefore, there are two compare match registers for one-phase
output, with the compare register containing the pre-change data, and the temporary register
containing the new data. In this interval, the three counters−TCNT_3, TCNT_4, and TCNTS−and
two registers−compare register and temporary register−are compared, and PWM output controlled
accordingly.
