INTERRUPT FLAG REGISTER (IFR)
LINF—LIN FLAG BIT
This read/write flag is set on the falling edge at the LIN
data line. Clear LINF by writing a logic [1] to LINF. Reset
clears the LINF bit. Writing a logic [0] to LINF has no effect.
1 = Falling edge on LIN data line has occurred.
0 = Falling edge on LIN data line has not occurred since
last clear.
HTF—HIGH TEMPERATURE FLAG BIT
This read/write flag is set on a high temperature condition.
Clear HTF by writing a logic [1] to HTF. If a high temperature
condition is still present while writing a logic [1] to HTF, the
writing has no effect. Therefore, a high temperature interrupt
cannot be lost due to inadvertent clearing of HTF. Reset
clears the HTF bit. Writing a logic [0] to HTF has no effect.
1 = High temperature condition has occurred.
