Rx 14 Mask (RX14MASK) register
This register is provided for legacy support and for MCUs that do not have the individual masking per
Message Buffer feature. Setting the BCC bit in MCR causes the RX14MASK register to have no effect on
the module operation.
RX14MASK is used as acceptance mask for the Identifier in Message Buffer 14. When the FEN bit in
MCR is set (FIFO enabled), the RXG14MASK also applies to element 6 of the ID filter table. This register
has the same structure as the Rx Global Mask register.
, for important details on usage of RX14MASK on filtering process for Rx
FIFO.
The contents of this register must be programmed while the module is in Freeze Mode, and must not be
modified when the module is transmitting or receiving frames.

Reset value: 0xFFFF_FFFF
25.4.4.6
Rx 15 Mask (RX15MASK) register
This register is provided for legacy support and for MCUs that do not have the individual masking per
Message Buffer feature. Setting the BCC bit in MCR causes the RX15MASK register to have no effect on
the module operation.
When the BCC bit is negated, RX15MASK is used as acceptance mask for the Identifier in Message Buffer
15. When the FEN bit in MCR is set (FIFO enabled), the RXG15MASK also applies to element 7 of the
ID filter table. This register has the same structure as the Rx Global Mask register.

Rx FIFO.
The contents of this register must be programmed while the module is in Freeze Mode, and must not be
modified when the module is transmitting or receiving frames.

Error Counter Register (ECR)
This register has two 8-bit fields reflecting the value of two FlexCAN error counters: Transmit Error
Counter (TX_ERR_COUNTER field) and Receive Error Counter (RX_ERR_COUNTER field)

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
