LIN Diagnostics
The ADuC7034 features the capability to nonintrusively 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. First, GPIO
must be configured as a GPIO through GP2CON[20], and then
the LIN pin can be pulled high or low using GP2DAT.

The ADuC7034 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, when HVSTA[3] is set),
LIN communication continues uninterrupted.
