Figure 44 : Example LIN Configuration
LIN Diagnostics
The ADuC7032 features the capability to non-intrusively
monitor the current state of the LIN pin. This read back
functionality is implemented via GPIO11. 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 GPIO12. To enable this
functionality GPIO12 must be configured as a GPIO via
GP2CON[20]. Once configured, the LIN pin may be pulled
high or low via GP2DAT.
The ADuC7032 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].
