High-speed CAN/LIN fail-safe system basis chip
6.8.5.2
LIN dominant clamping
When the LIN-bus is clamped dominant for longer than t
LIN(dom)(det)
(which is longer than
t
TXDL(dom)
), the state of the LIN termination is changed according to
Figure 12
.
6.8.5.3
LIN recessive clamping
If the LIN bus pin is clamped recessive while TXDL is driven dominant the LIN transmitter
is disabled. The transmitter is re-activated automatically when the LIN bus becomes
dominant or manually by setting and clearing the LTC bit.
6.9 Inhibit and limp home output
The INH/LIMP output pin is a 3-state output pin which can be used either as an inhibit for
an extra (external) voltage regulator, or as a ‘limp home’ output. The pin is controlled via
the ILEN bit and ILC bit in the System Configuration register; see
Figure 13
.
When pin INH/LIMP is used as inhibit output, a pull down resistor to GND ensures a
default LOW level. The pin can be set to HIGH according to the state diagram.
When pin INH/LIMP is used as limp home output, a pull up resistor to V
BAT42
ensures a
default HIGH level. The pin is automatically set to LOW when the SBC enters Fail-safe
mode.
