Set ABTCLR Automatic block transmission engine clear request bit

Request to clear the automatic block transmission engine. After the automatic block transmission

engine has been cleared, automatic block transmission is started from message buffer 0 by setting

the ABTTRG bit to 1.

Set ABTTRG Clear ABTTRG Automatic block transmission start bit

0 1 Request to stop automatic block transmission.

1 0 Request to start automatic block transmission.

Other than above No change in ABTTRG bit.

Caution Even if the ABTTRG bit is set (1), transmission is not immediately executed, depending on the

situation such as when a message is received from another node or when a message other

than the ABT message (message buffers 8 to 31) is transmitted.

Even if the ABTTRG bit is cleared (0), transmission is not terminated midway. If transmission

is under execution, it is continued until completed (regardless of whether transmission is

successful or fails).
