Detailed Description

The options are:

0 = DPWM(n) A Rising edge

1 = DPWM(n) A Falling edge

2 = DPWM(n) B Rising edge

3 = DPWM(n) B Falling edge

4 = DPWM(n+1) A Rising edge

5 = DPWM(n+1) A Falling edge

6 = DPWM(n+1) B Rising edge

7 = DPWM(n+1) B Falling edge

Where “n" is the numerical index of the DPWM module of interest. For example n=1 refers to DPWM1.

The Edge Gen is controlled by the DPWMEDGEGEN register. It also has an enable/disable bit.

The IntraMux is controlled by the Auto Config registers. Intra Mux is short for intra multiplexer. The

IntraMux takes signals from multiple DPWMs and from the Edge Gen and combines them logically to

generate DPWMA and DPWMB signals This is useful for topologies like phase-shifted full bridge,

especially when they are controlled with automatic mode switching. Of course, it can all be disabled, and

DPWMA and DPWMB will be driven as described in the sections above. If the Intra Mux is enabled, high

resolution must be disabled, and DPWM edge resolution goes down to 4 ns.

Figure 6-13 shows the Edge Gen/Intra Mux:

Figure 6-13. Edge Generation / IntraMux

Here is a list of the IntraMux modes for DPWMA:

0 = DPWMA(n) pass through (default)

1 = Edge-gen output, DPWMA(n)

2 = DPWNC(n)

3 = DPWMB(n) (Crossover)

4 = DPWMA(n+1)

5 = DPWMB(n+1)

6 = DPWMC(n+1)

7 = DPWMC(n+2)

8 = DPWMC(n+3)

and for DPWMB:

0 = DPWMB(n) pass through (default)

1 = Edge-gen output, DPWMB(n)

2 = DPWNC(n)
