Rx 14 Mask (RX14MASK)
This register is provided for legacy support and for low cost MCUs that do not have the
individual masking per Message Buffer feature. For MCUs supporting individual masks per
MB, setting the BCC bit in the MCR causes the RX14MASK register to have no effect on the
module operation.
RX14MASK is used as an acceptance mask for the Identifier in Message Buffer 14. When
the FEN bit in the MCR is set (FIFO enabled), the RX14MASK also applies to element 6 of
the ID filter table. This register has the same structure as the Rx Global Mask Register. It
must be programmed while the module is in Freeze Mode, and must not be modified when
the module is transmitting or receiving frames.
Rx 15 Mask (RX15MASK)
This register is provided for legacy support and for low cost MCUs that do not have the
individual masking per Message Buffer feature. For MCUs supporting individual masks per
MB, setting the BCC bit in the MCR causes the RX15MASK register to have no effect on the
module operation.

Mask Bits
For normal Rx MBs, the mask bits affect the ID filter programmed on the MB. For the Rx FIFO, the
mask bits affect all bits programmed in the filter table (ID, IDE, RTR).
0 The corresponding bit in the filter is “don’t care.”
1 The corresponding bit in the filter is checked against the one received.
