LIN Diagnostics
The ADuC7033 features the capability to unintrusively monitor
the current state of the LIN pin. This readback functionality is
implemented using GPIO_11. The current state of the LIN pin
is contained in GP2DAT[4].
It is also possible to drive the LIN 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 pin can be pulled
high or low using GP2DAT.

The ADuC7033 also features short-circuit protection on the LIN
pin. If a short-circuit condition is detected on the LIN pin,
HVSTA[2] is set. This bit is cleared by re-enabling 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, HVSTA[3] is set, LIN
communications continue uninterrupted.
