ADuC7023 PWM Dead Gap

Question

Hi All, 
 How can I get no overlapping PWM signals? The datasheet description isn't describe anything about PWM h-bridge. If some one can elaborate. 
 Thank You

Have a look at the aducm360 userguide which uses the same PWM block. You'll find more information there. 
 But basically if you use the circuit shown in the aducm360 userguide(figure 36), if you look at the timing diagram(Figure 34) the dead time is the difference between PWM0COM2 and PWM0COM1. (COM1 should be greater) 
 And the other deadtime is the difference between PWM0COM0 and PWM0LEN. 
 Hope that makes sense as it took me a bit of time to understand it. Let me know if you need me to clarify anything. 
 Regards,
