AWR1843: AWR1843 dcan mask unsing.

Part Number: AWR1843

Hi TI,

Issue description as below:

I try to masking CAN ID by setting some register mask function and following instruction  in document at page.2429 section Controller Area Network (DCAN)  . (https://www.ti.com/lit/pdf/swru520)

Only receive  CAN ID : 0x123. 

Sending CAN ID that is not 0x123 by PCAN. but RX interrupt is also triggered.

My configuration as blow:

My question is 

1. Does any config need to modify or not correct?

2.Even if the ID Mask function is set, does an interrupt occur for the received data of all IDs? Or should the RX interrupt be triggered only when an ID that has passed the ID Mask is received?

  • Hi,

    Please refer to the information provided in section 22.10 that describes the DCAN interrupts.
