10.2.2 Dead-time timer register
Figure 10.2.3 shows the structure of the Dead-time timer register.
The dead-time timer is used to count the time to prevent “L” level of positive waveform outputs from
overlapping with “L” level of their negative waveform outputs. (This time is referred to as “dead time.”)
Figure 10.2.4 shows the structure of the dead-time timer.
