bit 7 bit 0

Legend:

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 7 Unimplemented: Read as ‘0’

bit 6 RXRTR: Receiver Remote Transmission Request bit

1 = This is a remote transmission request

0 = This is not a remote transmission request

bit 5 RB1: Reserved bit 1

Reserved by CAN Spec and read as ‘0’.

bit 4 RB0: Reserved bit 0

Reserved by CAN Spec and read as ‘0’.
