BUFFER REGISTERS
Mode 0
Legend:
C = Clearable bit
‘1’ = Bit is set
bit 7
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:
This bit is set by the CAN module upon receiving a message and must be cleared
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.
