Bit error and Physical bus error in Lin communication


I am using RL78/f13.

Using Lin communication, trying to sense the status of the switch (slave) and RL78 (master).

Error detection register has been enabled (LEDE0 = 0x8F) .

 When header is transmitted continuously with adequate delay and slave is also responding, but when break point is placed at status interrupt, it enters and showing bit error and physical bus error (LEST0=0x03). It is entering status interrupt at every 131 count of header transmission.

How to rectify these errors?

Thank you
