22.2.4. CAN Register Assignment
The standard Bosch CAN registers are mapped to SFR space as shown below and their full definitions are
available in the CAN User’s Guide. The name shown in the Name column matches what is provided in the
CAN User's Guide. One additional SFR which is not a standard Bosch CAN register, CAN0CFG, is pro-
vided to configure the CAN clock. All CAN registers are located on SFR Page 0x0C.
