bit 7 bit 0
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 CANCKS: ECAN Module Clock (FCAN) Source Select bit
1 = FCAN is equal to twice F
P
0 = FCAN is equal to FP

101 = Reserved
100 = Set Configuration mode
011 = Set Listen Only Mode
010 = Set Loopback mode
001 = Set Disable mode
000 = Set Normal Operation mode
bit 7-5 OPMODE<2:0>: Operation Mode bits
111 = Module is in Listen All Messages mode
110 = Reserved
101 = Reserved
100 = Module is in Configuration mode
011 = Module is in Listen Only mode
010 = Module is in Loopback mode
001 = Module is in Disable mode
000 = Module is in Normal Operation mode
bit 4 Unimplemented: Read as ‘0’
bit 3 CANCAP: CAN Message Receive Timer Capture Event Enable bit
1 = Enable input capture based on CAN message receive
0 = Disable CAN capture
bit 2-1 Unimplemented: Read as ‘0’
