11.6.8 Receive Buffer Status Register

The following table lists the receive buffer status indicator register RX_BUF_STATUS and the bits descriptions of the register. For receive buffer, the status indicates if a message has arrived. This register consolidates the status of all receive message buffers.

Important: In case of Extended frame, the received message ID is stored in [31:3] bits of RX ID register. In case of Standard frame, the message ID is stored in [31:21] bits of RX ID register. Both message identifier (standard frame and extended frame) are stored at different bit position of RX ID register.
