Features
In standalone mode, the base frequency and PWM polarity are specified at the same time during
initialization by connecting either pin 25, 26, 27, or 28 exclusively to the PWMPOL_BASEFREQ input.
During initialization, pins 25, 26, 27, and 28 are cycled one at a time to determine which one has been
connected to the PWMPOL_BASEFREQ input.

made. Refer to the standalone mode schematic,
connected at any one time.

It is not necessary to break this connection once the initialization phase has
been completed. The MC3PHAC will function properly while this
connection is in place.
