bit 6-5
bit 4
bit 3
bit 2
bit 1
bit 0
bit 7
RXFUL: Receive Full Status bit
1 = Receive buffer contains a received message
0 = Receive buffer is open to receive a new message
RXM1:RXM0: Receive Buffer Mode bits
11 = Receive all messages (including those with errors)
10 = Receive only valid messages with extended identifier
01 = Receive only valid messages with standard identifier
00 = Receive all valid messages
Unimplemented: Read as ’0’
RXRTRRO: Receive Remote Transfer Request Read Only bit
1 = Remote transfer request
0 = No remote transfer request
RXB0DBEN: Receive Buffer 0 Double Buffer Enable bit
1 = Receive Buffer 0 overflow will write to Receive Buffer 1
0 = No Receive Buffer 0 overflow to Receive Buffer 1
JTOFF: Jump Table Offset bit (read only copy of RX0DBEN)
1 = Allows Jump Table offset between 6 and 7
0 = Allows Jump Table offset between 1 and 0
FILHIT0: Filter Hit bit
This bit indicates which acceptance filter enabled the message reception into receive buffer 0
1 = Acceptance Filter 1 (RXF1)
0 = Acceptance Filter 0 (RXF0)
Legend:
R = Readable bit
- n = Value at POR
RXFUL
R/C-0
Note:
Note:
This bit is set by the CAN module and should be cleared by software after the buffer
is read.
This bit allows same filter jump table for both RXB0CON and RXB1CON.
