Note 1:
Unimplemented registers are read as ‘0’.
2:
This is not a physical register.
3:
Contents of register are dependent on WIN2:WIN0 bits in the CANCON register.
4:
CANSTAT register is repeated in these locations to simplify application firmware. Unique names are given
for each instance of the CANSTAT register due to the Microchip header file requirement.
for each instance of the CANSTAT register due to the Microchip header file requirement.
5:
These registers are not implemented on the PIC18F248 and PIC18F258.
