Tiva^™ TM4C129CNCZAD Microcontroller
Register 7: CAN Baud Rate Prescaler Extension (CANBRPE), offset 0x018
This register is used to further divide the bit time set with the BRP bit in the CANBIT register. It is
write-enabled by setting the CCE bit in the CANCTL register.

Reset Description
0x0000.000 Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.

Baud Rate Prescaler Extension
0x00-0x0F: Extend the BRP bit in the CANBIT register to values up to
1023. The actual interpretation by the hardware is one more than the
value programmed by BRPE (MSBs) and BRP (LSBs).
