TMS570LS1227: CAN stop frame sending

Part Number: TMS570LS1227

Dear team,

Does TMS570LS1227 CAN has the function which can stop frame sending in Can Core?  I found other Microcontrollers have this sort of function, can be forced to stop the data that is currently being repeated to send and clear the data in the buffer。Does this product have this function?

BR,

    Hi Susan,

    The CAN module in our device is implemented according to ISO 11989-1, and supports CAN protocol version 2.0 part A, B.

    The application has to update the data of the messages to be transmitted and enable and request their transmission. After the transmit is started by writing the message number to IFxCMD, the busy bit is automatically set to 1 to indicate the a transfer is in process. At this moment, you are not able to stop the data transfer.

    If you have write the data to CAN RAM and want to change them before sending, you can update the transmit object or change the transmit object by setting IFxCMD register and Data Register.
