In both Synchronous and Asynchronous Steering modes, the modulated input signal can be steered to any combination of four CWG outputs. A fixed-value will be presented on all the outputs not used for the PWM output. Each output has independent polarity, steering, and shutdown options. Dead-band control is not used in either steering mode.

Steering Modes)
For example, when STRA =
0 then the corresponding pin is held at the
level defined by OVRA. When STRA =
1, then the pin is driven by the modulated input
signal.The POLy bits control the signal polarity only when STRy = 1.
The CWG auto-shutdown operation also applies in Steering modes as
described in Auto-Shutdown”. An auto-shutdown event will only affect pins that have STRy = 1.
