- CPU confirms Tx completion
of message buffer 6, 9, and 2.
- Tx completion of message
buffer 3, and 4.
Event:

- Message buffer 8, 5, 6, and 10 completes transmission.
- THL is full.
- TOVF bit is set to 1.

- Message buffer 11, 13, and 14
completes transmission.
- Overflow situation occurs.
Event:
TOVF bit = 1
LOPT is blocked
TOVF bit = 1
LOPT is blocked
TOVF bit = 1 denotes that LOPT equals TGPT − 1 while message buffer number stored to element indicated by LOPT − 1.
