Example Code
LIN Diagnostics
The ADuC7032-8L features the capability to nonintrusively
monitor the current state of the LIN pin. This readback
functionality is implemented via 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 via 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 via GP2CON[20]. Once configured, the LIN pin can be
pulled high or low via GP2DAT.
The ADuC7032-8L 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 via HVCFG1[3]. It is possible to disable this feature via
HVCFG1[2].
