Thermal Shutdown
In thermal shutdown, the LIN bus output is disabled
instantaneously. The output transistor is turned off,
regardless of the input level at pin LINTX bit and only a
limited current can flow into the receiver connected to
the LIN bus pin.

Wake-up from SLEEP upon Bus
Activity
The PIC16C433 can Wake-up from SLEEP upon bus
activity in the following way:
1.
Connect BACT to one of GPIO<0:3> pins.
The BACT output is a CMOS-levels representation of
the LIN pin. This signal can be routed to one of the
GPIO<0:3> pins. The GPIO<2> external interrupt or
GPIO<0:1,3> interrupt-on-change wakes up the device
from SLEEP. Any one of the four GPIO pins can be
used for wake-up where GPIO<2> offers multiple con-
figuration options (Section 9.5.2) and GPIO<0:1,3> are
interrupt-on-change (Section 9.5.3).

Note:
No resistor or diode is required between
VBAT pin and 12V supply and for slave con-
figuration.
Note:
TLINRX must be set to ‘1’ at all times.
Note:
BACT pin is an output and must be left
open if unused.
