The CnGMABT register is used to control the automatic block transmission
(ABT) operation.
(a) Read
Note
1.
Set the ABTCLR bit to 1 while the ABTTRG bit is cleared to 0.
The operation is not guaranteed if the ABTCLR bit is set to 1 while the
ABTTRG bit is set to 1.
2.
When the automatic block transmission engine is cleared by setting the
ABTCLR bit to 1, the ABTCLR bit is automatically cleared to 0 as soon as
the requested clearing processing is complete.
Caution
Do not set the ABTTRG bit in the initialization mode. If the ABTTRG bit is set in
the initialization mode, the operation is not guaranteed after the CAN module
has entered the normal operation mode with ABT.
After reset: 0000H
