SRS0:SRS1—LIN Slew Rate Selection Bits
appropriate LIN slew rate for different baud rate configurations
as shown in
programming via the LIN and are not intended for use in the
application.
GS—Go to STOP Mode Bit
go into STOP mode. Reset or CPU interrupt requests clear the
GS bit.
System Control Register (SYSSTAT)
HP_OCF—Hall-Effect Sensor Input Terminal Overcurrent
Flag Bit
of the Hall-effect sensor input terminals. Clear HP_OCF and
enable the output by writing a logic [1] to the HP_OCF flag.
Reset clears the HP_OCF bit. Writing a logic [0] to HP_OCF
has no effect.
LINCL — LIN Current Limitation Bit
current limitation region. Due to excessive power dissipation in
the transmitter, software is advised to turn the transmitter off
immediately.
