These bits can only be changed in Configuration mode. See Register 23-1 to change to Configuration mode.
This bit is used in Mode 2 only.
FIFO length of 4 or less will cause this bit to be set.
MDSEL1:MDSEL0: Mode Select bits
00 = Legacy mode (Mode 0, default)
01 = Enhanced Legacy mode (Mode 1)
10 = Enhanced FIFO mode (Mode 2)
11 = Reserved
FIFOWM: FIFO High Water Mark bit
1 = Will cause FIFO interrupt when one receive buffer remains
0 = Will cause FIFO interrupt when four receive buffers remain
EWIN4:EWIN0: Enhanced Window Address bits
These bits map the group of 16 banked CAN SFRs into access bank addresses 0F60-0F6Dh. Exact
group of registers to map is determined by binary value of these bits.
