Legend:

R = Readable bit

-n = Value at POR

HC = Hardware Clear

W = Writable bit

‘1’ = Bit is set

S = Settable bit

U = Unimplemented bit, read as ‘0’

‘0’ = Bit is cleared

x = Bit is unknown

bit 31-28 Unimplemented: Read as ‘0’

bit 27 ABAT: Abort All Pending Transmissions bit

1 = Signal all transmit buffers to abort transmission

0 = Module will clear this bit when all transmissions aborted

bit 26-24 REQOP<2:0>: Request Operation Mode bits

111 = Set Listen All Messages mode

110 = Reserved

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 23-21 OPMOD<2:0>: Operation Mode Status 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 20 CANCAP: CAN Message Receive Time Stamp Timer Capture Enable bit

1 = CANTMR value is stored on valid message reception and is stored with the message

0 = Disable CAN message receive time stamp timer capture and stop CANTMR to conserve power

bit 19-16 Unimplemented: Read as ‘0’

bit 15 ON: CAN On bit(1)

1 = CAN module is enabled

0 = CAN module is disabled

bit 14 Unimplemented: Read as ‘0’

Note 1: If the user application clears this bit, it may take a number of cycles before the CAN module completes the

current transaction and responds to this request. The user application should poll the CANBUSY bit to

verify that the request has been honored.
