16 Motor Control PWM (PWM)
• Modes 6 and 7: Bypass delay on falling edge (FED) or rising edge (RED)
In these modes, either RED (Rising Edge Delay) or FED (Falling Edge Delay) is bypassed. As a result, the
corresponding delay is not applied.
Mode Mode Description
1 PWMxA and PWMxB Pass Through/No Delay
2 Active High Complementary (AHC), see Figure
3 Active Low Complementary (ALC), see Figure
4 Active High (AH), see Figure
5 Active Low (AL), see Figure
6 PWMxA Output = PWMxA In (No Delay)
PWMxB Output = PWMxA Input with Falling Edge Delay
7 PWMxA Output = PWMxA Input with Rising Edge Delay
PWMxB Output = PWMxB Input with No Delay
Note: For all the modes above, the position of the binary switches S4 to S8 is set to 0.
