Advanced Information
; Clear the interrupt flag
; This is either TX or RX interrupt
; Clear CANCON.WIN bits before copying
; new ones.
; Use previously saved CANCON value to
; make sure same value.
; Copy masked value back to TempCANCON
; Retrieve ICODE bits
; Use previously saved CANSTAT value
; to make sure same value.
; Copy ICODE bits to WIN bits.
; Copy the result to actual CANCON
; Preserve current non WIN bits
; Restore original WIN bits
