Figure 17-4 shows the transition of operation modes. Table 17-6 describes the transition conditions of operation modes.
Figure 17-4. Transition of Operation Modes
Table 17-6. Transition Conditions of Operation Modes
Step Operation mode transition Transition condition
(1) LIN reset mode → LIN mode
-LIN operation mode
LMD bits in LMDn register = 00b or 10b or
11b
and
OM1 and OM0 bits in LCUCn register = 11b
(2) LIN reset mode → LIN mode
-LIN wake-up mode
LMD bits in LMDn register = 00b or 10b or
11b
and
OM1 and OM0 bits in LCUCn register = 01b

Note 1
LIN mode
-LIN operation mode
-LIN wake-up mode
→ LIN reset mode OM0 bit in LCUCn register = 0b
(4)
Note 2
LIN mode
-LIN operation mode
→ LIN mode
-LIN wake-up mode
OM1 and OM0 bits in LCUCn register = 01b
(5)
Note 2
LIN mode
-LIN wake-up mode
→ LIN mode
-LIN operation mode
OM1 and OM0 bits in LCUCn register = 11b
Notes 1. When the LIN/UART module makes a transition from the LIN operating mode to the LIN reset mode while
operating as a LIN slave (at a fixed baud rate), write 1 to the LIN0EN bit (or the LIN1EN bit) in the PER2
register after having cleared the given bit to 0.
2. Transition between LIN operation mode and LIN wake-up mode cannot be made when communication is
going on (when the FTS bit in the LTRCn register is 1).
