Figure 27-20. PWM 16-Bit Mode
Left- or center-aligned output mode can be used in concatenated mode and is controlled by the low order
CAEn bit. The high order CAEn bit has no effect. The table shown below is used to summarize which
channels are used to set the various control bits when in 16-bit mode.
27.3.2.8 PWM Boundary Cases
The following table summarizes the boundary conditions for the PWM regardless of the output mode (left-
or center-aligned) and 8-bit (normal) or 16-bit (concatenation):
