Legend: C = Writable bit, but only ‘0’ can be written to clear the bit r = Bit is Reserved
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15-14 Unimplemented: Read as ‘0’
bit 13 CSIDL: Stop in Idle Mode bit
1 = Discontinue module operation when device enters Idle mode
0 = Continue module operation in Idle mode
bit 12 ABAT: Abort All Pending Transmissions bit
1 = Signal all transmit buffers to abort transmission
0 = Module will clear this bit when all transmissions are aborted
bit 11 Reserved: Do not use

110 = Reserved
111 = Set Listen All Messages mode
bit 7-5 OPMODE<2:0>: Operation Mode bits
000 = Module is in Normal Operation mode
001 = Module is in Disable mode
010 = Module is in Loopback mode
011 = Module is in Listen Only mode
100 = Module is in Configuration mode
101 = Reserved
