When using the CAN interrupt, the C0SISTR register indicates which message slot is requesting an
interrupt. The SISj bits (j=0 to 15) are not automatically set to "0" (no interrupt requested) when an
interrupt is acknowledged. Set the SISj bits to "0" by program.
Use the MOV instruction, instead of the bit clear instruction, to set the SISj bits to "0". The SISj bits,
which are not being changed to "0", must be set to "1".
Refer to 23.4 CAN Interrupt for details.

23.1.11.1 Message Slot for Transmission
23.1.11.2 Message Slot for Reception
The SISj bit is set to "1" (interrupt requested) when the C0TSR register is stored into the message slot
j after data transmission is completed.
The SISj bit is set to "1" (interrupt requested) when the received message is stored in the message slot
j after data reception is completed.
