F2837xD CAN interrupt configuration

Gianluca Botto

Jason,

there is another thing I can not undertand (probably this time I'm missing something): regarding CAN module, how can I set which of the the two interrupt lines are triggered by the single mailbox IntPnd flag? It seems that the CAN_IP_MUX21 Register is read-only.

Thank you.

Gianluca,

The CAN_IP_MUX21 register is actually R/W. I'll make sure the documentation error gets corrected.

Thanks,

TIs,

I've noticed some weird behaviors accessing the IFx registers by bit fields (Not only CAN_IFxCMD as it is expected, but also CAN_IFxMSK for example).

Only 32-bit accesses seem to work well; is this thing known or I'm doing something wrong?

Thank you.

BR,

Gianluca
