Section 16 Controller Area Network (HCAN)
16.2.3
The bit configuration register (BCR) is a 16-bit readable/writable register that is used to set CAN
bit timing parameters and the baud rate prescaler.
Bits 15 and 14—Resynchronization Jump Width (SJW): These bits set the bit synchronization
range.
Bit 15:
BCR7
