DescriptionValue
Control bits unchanged.0
Transfer control bits from the CANIFnMCTL register
into the Interface registers.

0RWCONTROL4
Clear Interrupt Pending Bit
The function of this bit depends on the configuration of the WRNRD bit.
DescriptionValue
If WRNRD is clear, the interrupt pending status is transferred
from the message buffer into the CANIFnMCTL register.
If WRNRD is set, the INTPND bit in the message object remains
unchanged.
0
If WRNRD is clear, the interrupt pending status is cleared in the
message buffer. Note the value of this bit that is transferred
to the CANIFnMCTL register always reflects the status of the
bits before clearing.
If WRNRD is set, the INTPND bit is cleared in the message
object.

0RWCLRINTPND3
NEWDAT / TXRQST Bit
The function of this bit depends on the configuration of the WRNRD bit.
DescriptionValue
If WRNRD is clear, the value of the new data status is transferred
from the message buffer into the CANIFnMCTL register.
If WRNRD is set, a transmission is not requested.
0
If WRNRD is clear, the new data status is cleared in the message
buffer. Note the value of this bit that is transferred to the
CANIFnMCTL register always reflects the status of the bits
before clearing.
If WRNRD is set, a transmission is requested. Note that when
this bit is set, the TXRQST bit in the CANIFnMCTL register is
ignored.
