- check return code of enqueue_modulation_timings
- wrap all hardware access to safety critical hardware timer registers in safety_critical_ sections. These functions like the armed-ness of each PWM output to a corresponding armed state that can only be set at start or by the user
- ensure NaN in any variables doesn't cause unpredictable behavior on the safety critical PWM outputs
These two activities are now separate states of the axis state machine.
Each of them can be invoked independently at any time (provided the motor is calibrated).
