BTR (CAN) Register Description
| Register Name | BTR |
|---|---|
| Offset Address | 0x000000000C |
| Absolute Address |
0x00FF06000C (CAN0) 0x00FF07000C (CAN1) |
| Width | 32 |
| Type | rwNormal read/write |
| Reset Value | 0x00000000 |
| Description | Bit Timing and Synchronization |
The Bit Timing Register (BTR) specifies the bits needed to configure bit time. Specifically, the Propagation Segment, Phase segment 1, Phase segment 2, and Synchronization Jump Width (as defined in CAN 2.0A, CAN 2.0B and ISO 11891-1) are written to the BTR. The actual value of each of these fields is one more than the value written to this register.
