After each LIN error, the LIN controller stops its previous activity and returns to its withdrawal
mode (LCMD[2..0] = 000
Writing 1 in LERR of LINSIR register resets LERR bit and all the bits of the LINERR register.
According to the LIN protocol, a frame time-out error is flagged if: T
This feature is implemented in the LIN/UART controller.

Overrun error will be flagged if a new command (other than LIN Abort) is entered while
‘Busy signal’ is present.
In UART mode, an overrun error will be flagged if a received byte overwrites the byte stored
in the serial input buffer.
LIN abort transfer reflects a previous LIN Abort command (LCMD[2..0] = 000) while ‘Busy
signal’ is present.
