| 15:8 | USER_DATA | R | 0h | Received User Data This field contains the 8-bit user data field of the last successfully received frame. |
| 7:5 | RESERVED_1 | R | 0h | Reserved |
| 4:1 | FRAME_TAG | R | 0h | Received Frame Tag This field contains the 4-bit frame tag from the last successfully received frame. This is intentionally shifted into bits 4:1 so that the register can be used as a 32-bit address index based on the received tag. |
| 0 | ZERO | R | 0h | Zero bit This bit will always read as 0. This is intentionally provided to create a 32-bit offset if required. Using the FRAME_TAG and ZERO bits of this register [bits 4:0], application software can directly index into an array of 32-bit data. |
