Note 1: Shaded registers are available in Access Bank low area, while the rest are available in Bank 15.
2: CANSTAT register is repeated in these locations to simplify application firmware. Unique names are given
for each instance of the controller register due to the Microchip header file requirement.
3: These registers are not CAN registers.
4: Unimplemented registers are read as ‘0’.
