Thanks for your patch!

Just some bikeshedding on the exact naming below ;-)

s/receive/rx/?

Some are also a bit long to type.
Perhaps use naming closer to the User's Manual?

INTRCANGERR => g_err
INTRCANGRECC => g_recc
INTRCAN0ERR => ch0_err
INTRCAN0REC => ch0_rec
INTRCAN0TRX => ch0_trx
INTRCAN1ERR => ch1_err
INTRCAN1REC => ch1_rec
INTRCAN1TRX => ch1_trx

These do not have "_int" suffixes...

... and these do have "_int" suffixes.
