23.1.11.1 Message Slot for Transmit Operation
23.1.11.2 Message Slot for Receive Operation
When using the CAN interrupt, the CiSISTR register (i = 0, 1) indicates which message slot has requested an
interrupt. The SISj bit (j = 0 to 15) is not automatically set to 0 (interrupt not requested) even if the interrupt is
acknowledged. Set the SISj bit to 0 by a program.
Use the MOV instruction to set the SISj bits to 0. Write a 0 to the bit which is to set to 0, and write a 1 to the bit
which is to remain unchanged.
Refer to 23.4 CAN Interrupts for details.
The SISj bit becomes 1 (interrupt requested) when the value of the CiTSR register is stored into the message
slot j after a transmit operation is completed.
The SISj bit becomes 1 (interrupt requested) when the receive message is stored in the message slot j after a
receive operation is completed.
NOTES:

simultaneously, the SISj bit becomes 1.
(interrupt request enabled), the SISj bit becomes 1 at the completion of the transmit operation or at the
completion of the receive operation.
