66.6.32 MCAN Receive Buffer / FIFO Element Size Configuration

This register can only be written if the bits CCE and INIT are set in MCAN CC Control Register.

Configures the number of data bytes belonging to a Receive Buffer / Receive FIFO element. Data field sizes >8 bytes are intended for CAN FD operation only.

In case the data field size of an accepted CAN frame exceeds the data field size configured for the matching Receive Buffer or Receive FIFO, only the number of bytes as configured by MCAN_RXESC are stored to the Receive Buffer resp. Receive FIFO element. The rest of the frame’s data field is ignored.
