CAN 0 Media Arbitration Register 0 (C0MA0)
CAN 0 Media Arbitration Register 1 (C0MA1)
CAN 0 Media Arbitration Registers 0 and 1 (C0MA0 and C0MA1). These registers function as the arbitration field when performing
the media identification test. If MDME = 0, the media identification test cannot be performed and the contents of these registers is
ignored. If MDME = 1, the CAN module performs an additional qualifying test on data bytes 0 and 1 of the incoming message, as men-
tioned in the description of the CAN media ID mask registers. These registers can only be modified during a software initialization
(SWINT = 1).
r = read, w = write (allowed only when SWINT = 1 via C0DP/C0DB)
