allowed to source current as commanded by the primary processor. The primary processor can monitor
the condition of its switch with the analog current feedback measurement.
There are two LEDs on every PLUS+1
software control of the primary processor. Before the primary processor's application software starts
running, the green LED will be on and the red LED will be off.
Each LED light pipe will have an alternate yellow color which the application software will not have
access to. These alternate yellow colors will be used to indicate low-level software and/or hardware
failures. The yellow LED shared with the green LED light pipe will be controlled by the primary processor,
and the yellow LED shared with the red LED light pipe will be controlled by the secondary controller.
When either yellow LED is enabled the signal will override its shared green or red LED.
Recovery
1. The kernel will automatically disable the output.
2. The primary application must set the output to the off-state for a
minimum of 250 ms.
3. The kernel then clears status bit 4 and re-enables the output.
1. The primary application must select a valid output mode.
2. The kernel then clears status bit 5.
1. The controller must be reset by performing a power cycle.
1. The Safety FET must be off for 250 ms.
2. The primary application must command the output to the off-state.
3. The secondary application can then re-enable the output.
1. The primary application must command ALL outputs to the off-state.
2. The supply voltage must return to its valid range.
3. The kernel then clears status bit 8.
