Figure 23-4. LINFlex in loop back mode
This mode is provided for self test functions. To be independent of external events, the LIN core ignores
the LINRX signal. In this mode, the LINFlex performs an internal feedback from its Tx output to its Rx
input. The actual value of the LINRX input pin is disregarded by the LINFlex. The transmitted messages
can be monitored on the LINTX pin.
23.6.2
Self Test mode
LINFlex can be put in Self Test mode by setting the LBKM and SFTM bits in the LINCR. This mode can
be used for a Hot Self Test, meaning the LINFlex can be tested as in Loop Back mode but without affecting
a running LIN system connected to the LINTX
and LINRX pins. In this mode, the LINRX
pin is
disconnected from the LINFlex and the LINTX
pin is held recessive.
