OUTPUT CONTROL
2.20.1
Output Enable
The output enable switch selects between the PORT latch output and the PSMC
channel. When the PORT latch output is selected, then the output pin is not affected by
the PSMC. When the PSMC channel is selected, then the pin is not affected by the
PORT latch.
channel. When the PORT latch output is selected, then the output pin is not affected by
the PSMC. When the PSMC channel is selected, then the pin is not affected by the
PORT latch.
2.20.2
Output Steering
Two modes, SPWM and SPWMC, include steering. Steering gives the ability to steer
the PWM output to one or more of the six outputs. Steering differs from the output
enable because when steering is disabled then the pin output is forced false regardless
of the PORT latch level.
Modes other than SPWM and SPWMC do not include steering and therefore, all
steering controls are shown as connected for those modes and cannot be
disconnected.

2.20.3
Output Steering Synchronization
The checkbox in the lower left of the control selects period event steering
synchronization. When the PWM is active and steering is changed, then the
synchronized steering change takes effect at the period event immediately following
the change. When steering synchronization is not enabled then steering changes take
effect immediately without waiting for the period event.
