26.8.7 Three phase AC mode
The three-phase AC-mode is selected by setting the ACMODE bit in the CON register.
In this mode, the value of channel 0’s TC is routed to all channels for comparison with
their MAT registers. (The LIM1-2 registers are not used.)
Each channel controls its MCO output by comparing its MAT value to TC0.
Figure 79
The POLA bits are set to 0 for all three channels, so that for all MCO outputs the active
levels are high and the passive levels are low. Each channel has a different MAT value
which is compared to the TC0 value. In this mode the period value is identical for all three
channels and is determined by LIM0. The dead-time mode is disabled.
