EX/ST = 0
MEME = 0: Mask register ignored. ID and
arbitration register must match exactly.
MEME = 1: Only bits corresponding to 1 in mask
register are compared in ID and arbitration
registers.
EX/ST = 1
MEME = 0: Mask register ignored. ID and
arbitration register must match exactly.
MEME = 1: Only bits corresponding to 1 in mask
register are compared in ID and arbitration
registers.
MDME = 0: Media byte arbitration disabled.
MDME = 1: Only bits corresponding to 1 in
Media ID mask register are compared between
data bytes 1 and 2 and Media arbitration
registers.
EX/ST = 0
MEME = 0: Mask register ignored. ID and
arbitration register must match exactly.
MEME = 1: Message center 15 mask registers
are ANDed with Global Mask register. Only bits
corresponding to 1 in resulting value are
compared in ID and arbitration registers.
