bit 3
Mode 1, 2
Mode 0
RXFUL: Receive Full Status bit
1 = Receive buffer contains a received message
0 = Receive buffer is open to receive a new message
Mode 0:
RXM1: Receive Buffer Mode bit 1
Combines with RXM0 to form RXM<1:0> bits (see bit 5).
11 = Receive all messages (including those with errors); filter criteria is ignored
10 = Receive only valid messages with extended identifier; EXIDEN in RXFnSIDL must be ‘1’
01 = Receive only valid messages with standard identifier, EXIDEN in RXFnSIDL must be ‘0’
00 = 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
0 = Receive all valid messages as per acceptance filters
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)
1 = A remote transmission request is received
0 = A remote transmission request is not received
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>.
Mode 0:
RXRTRRO: Remote Transmission Request bit for Received Message (read-only)
1 = A remote transmission request is received
0 = 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>.

Note 1: This bit is set by the CAN module upon receiving a message and must be cleared
(1)
(1)
by software after the buffer is read. As long as RXFUL is set, no new message will
be loaded and buffer will be considered full.
