• The emergency dead time insertion is implemented after the 'ideal'
PWM output pair, including crossover, is generated.
• The output control unit allows the redirection of the outputs of the
two-phase timing unit for each channel to either the high-side or
the low-side output. In addition, the output control unit allows
individual enabling/disabling of each of the four PWM output
signals.
• The PWM interrupt controller generates an interrupt at the start of
the PWM period which is shared for all modules.
