2.0 USING THE PIC16F1829LIN IN
LIN BUS APPLICATIONS
Note:
Failure to follow the recommended setup
and initialization may result in improper or
unknown LIN operation.
2.1 Hardware
The PIC16F1829LIN internal connections are
optimized to reduce the number of components in a
typical LIN/J2602 node in a LIN bus system. Some
features and modules of the stand-alone PIC16F1829
are no longer available or their functionality has
changed.

For this reason, the following figure (Figure 2-2) is a
recommended block diagram. Note that the
microcontroller is powered by the internal voltage
regulator and an external connection must be made
between VREG and VBB along with a load capacitor.
FAULT/TXE can be monitored or controlled by any I/O
pin.
