bit 7 bit 0
bit 7-0 RXBnDm7:RXBnDm0: Receive Buffer n Data Field Byte m bits (where 0 ≤ n < 1 and 0 < m < 7)
Each receive buffer has an array of registers. For example, Receive Buffer 0 has 8 registers:
RXB0D0 to RXB0D7.
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
R-0 R-0 R-0 R-0 R-0 R-0 R-0 R-0
REC7 REC6 REC5 REC4 REC3 REC2 REC1 REC0
bit 7 bit 0
bit 7-0 REC7:REC0: Receive Error Counter bits
This register contains the receive error value as defined by the CAN specifications.
When RXERRCNT > 127, the module will go into an error passive state. RXERRCNT does not
have the ability to put the module in “Bus-Off” state.
