the following: each underflow occurrence in timer A or each valid edge input of an external signal. The pulse
output port mode consists of pulse output port 0 and pulse output port 1. These two circuits have the
equivalent functions and operate independently each other. Each of pulse output port 0 and pulse output
port 1 has two operation modes as listed in Table 9.1.1. Table 9.1.2 lists the overview of pulse output port
0; Table 9.1.3 lists the overview of pulse output port 1.
Note: The pulse output pins, where pulse width modulation is to be applied, determine the timer to be used.
