Receive Interrupt Node Pointer
Bitfield RXINP determines which interrupt node is
triggered by a message object receive event, if bitfield
RXIE in register MSGCTRn is set.
000_B CAN interrupt node 0 is selected.
……
111_B CAN interrupt node 7 is selected.
Transmit Interrupt Node Pointer
Bitfield TXINP determines which interrupt node is
triggered by a message object transmit event, if bitfield
TXIE in register MSGCTRn is set.
000_B CAN interrupt node 0 is selected.
……
111_B CAN interrupt node 7 is selected.
Reserved; returns ‘0’ if read; should be written with ‘0’.
1) The maximum number of data bytes is 8. A value > 8 written by the CPU, is internally corrected to 8 but the
content of bitfield DLC is not updated.
If a received data frame contains a data length code value > 8, only 8 bytes are taken into account. A read
access to bitfield DLC returns the original value of the DLC field of the received data frame.
The FIFO/gateway control register MSGFGCRn contains bits to enable and to control
the FIFO functionality, the gateway functionality and the desired transfer actions.
