| Description | 32 ID regs for TxEvent msgs 0 to 31 at 0x2000, 0x2008, etc (0x08 step) |
There can be up to 32 Tx Events stored in the Tx FIFO. The first Tx event ID register is stored at offset 0x2000. Second Tx event ID is at 0x2008. The address increment between registers is 0x008. Software Driver name: TEF_ID Original Bit Field Engineering Name: AIID
TxEvent_ID_Reg_n (CANFD) Register Bit-Field Summary
| Field Name | Bits | Type | Reset Value | Description |
|---|---|---|---|---|
| ID | 31:21 | roRead-only | 0 | Standard Message ID The Identifier portion for a Standard Frame is 11 bits. These bits indicate the Standard Frame ID. This field is valid for both CAN and CAN FD Standard and Extended Frames. |
| SRR_RTR_RRS | 20 | roRead-only | 0 | Substitute Remote Transmission Request For Extended CAN frames and Extended CAN FD frame this bit is transmitted at SRR position of the respective frame and must be set as 1. For Standard CAN FD frame this bit is transmitted at RRS position of the frame and must be set as 0. This bit differentiates between standard CAN data frames and standard CAN remote frames as the following: 1 = indicates that the message frame is a Standard Remote CAN Frame 0 = indicates that the message frame is a Standard Data CAN Frame Note: There are no CAN FD remote frames. |
| IDE | 19 | roRead-only | 0 | Identifier Extension This bit differentiates between frames using the Standard Identifier and those using the Extended Identifier. Valid for both CAN and CAN FD Standard and Extended Frames. 1 = indicates the use of an Extended Message Identifier 0 = indicates the use of a Standard Message Identifier |
| ID_EXT | 18:1 | roRead-only | 0 | Extended Message ID. This field indicates the Extended Identifier. Valid only for Extended CAN and CAN FD Frames. For Standard CAN and CAN FD Frames, writes to this field should be 0. |
| RTR_RRS | 0 | roRead-only | 0 | Remote Transmission Request. This bit differentiates between CAN extended data frames and CAN extended remote frames. 1 = indicates the message frame is a CAN Remote Frame 0 = indicates the message frame is a CAN Data Frame For Extended CAN FD frame this bit is transmitted at RRS position of the frame and must be set as 0. For Standard CAN and CAN FD Frames, writes to this bit should be 0. Note: There are no CAN FD remote frames. |
