Access new data bit
Clear NEWDAT bit in the message object.
NEWDAT bit remains unchanged.
Remark: A read access to a message object
can be combined with the reset of the control
bits INTPND and NEWDAT in IF1/2_MCTRL.
The values of these bits transferred to the IFx
Message Control Register always reflect the
status before resetting these bits.
Clear interrupt pending bit.
Clear INTPND bit in the message object.
INTPND bit remains unchanged.
Access control bits
Transfer control bits to IFx message buffer.
Control bits unchanged.
Access arbitration bits
Transfer Identifier, DIR, XTD, and MSGVAL
bits to IFx message buffer register.
Arbitration bits unchanged.
Access mask bits
Transfer Identifier MASK + MDIR + MXTD to
IFx message buffer register.
Mask bits unchanged.
Read transfer
Transfer data from the message object
addressed by the command request register
to the selected message buffer registers
CANIFn_CMDREQ.
