bit 7

RXFUL: Receive Full Status bit(1)

= Receive buffer contains a received message

= Receive buffer is open to receive a new message

bit 6

Mode 0:

RXM1: Receive Buffer Mode bit 1

Combines with RXM0 to form RXM<1:0> bits (see bit 5).

= Receive all messages (including those with errors); filter criteria is ignored

= Receive only valid messages with extended identifier; EXIDEN in RXFnSIDL must be ‘1’

= Receive only valid messages with standard identifier; EXIDEN in RXFnSIDL must be ‘0’

= Receive all valid messages as per EXIDEN bit in RXFnSIDL register

Mode 1, 2:

RXM1: Receive Buffer Mode bit 1

= Receive all messages (including those with errors); acceptance filters are ignored

= Receive all valid messages as per acceptance filters

bit 5

Mode 0:

RXM0: Receive Buffer Mode bit 0

Combines with RXM1 to form RXM<1:0> bits (see bit 6).

Mode 1, 2:

RTRRO: Remote Transmission Request bit for Received Message (read-only)

= A remote transmission request is received

= A remote transmission request is not received

bit 4

Mode 0:

Unimplemented: Read as ‘0’

Mode 1, 2:

FILHIT4: Filter Hit bit 4

This bit combines with other bits to form filter acceptance bits <4:0>.

bit 3

Mode 0:

RXRTRRO: Remote Transmission Request bit for Received Message (read-only)

= A remote transmission request is received

= A remote transmission request is not received

Mode 1, 2:

FILHIT3: Filter Hit bit 3

This bit combines with other bits to form filter acceptance bits <4:0>.
