Preliminary W79E217A Data Sheet
Figure 14-13: Override bit in complementary mode
Assume rising edge dead time insertion; refer to Figure 14-12: Override Flow Diagram.
Example: POVM0 = 1 and POVM1 = 0; PWM0EN and PWM1EN = 1;
a. Odd override bits have no effect in complementary mode.
b. Even override bit is activated, which causes the Odd PWM to deactivate.
c. Dead-Time insertion.
d. Even PWM activated after the dead-time.
e. Even override bit is deactivated, which causes the Even PWM to deactivate.
f. Dead-Time insertion.
g. Odd PWM is activated after the dead time.
