LIN Diagnostics
The ADuC7036 features the capability to nonintrusively monitor
the current state of the LIN/BSD pin. This readback
functionality is implemented using GPIO_11. The current state
of the LIN/BSD pin is contained in GP2DAT[4].
It is also possible to drive the LIN/BSD pin high and low
through user software, allowing the user to detect open-circuit
conditions. This functionality is implemented via GPIO_12. To
enable this functionality, GPIO_12 must be configured as a
GPIO through GP2CON[20]. After it is configured, the
LIN/BSD pin can be pulled high or low using GP2DAT.

The ADuC7036 also features short-circuit protection on the
LIN/BSD pin. If a short-circuit condition is detected on the
LIN/BSD pin, HVSTA[2] is set. This bit is cleared by reenabling
the LIN driver using HVCFG1[3]. It is possible to disable this
feature through HVCFG1[2].
LIN Operation During Thermal Shutdown
When a thermal event occurs, that is, when HVSTA[3] is set,
LIN communications continue uninterrupted.
