Memory Map and Register Definition
13.3.23 MSCAN Receive and Transmit Buffer Identifier Register 1 -
The identifier registers for an extended format identifier consists of a total of 32 bits: the
ID[28:0], SRR, IDE, and RTR bits.
Addresses: CAN_RXFG_IDR1 (Extended) – F440h base + 21h offset = F461h

This read-only bitfield is reserved and always has the value zero.
Extended Format Identifier
The identifiers consist of 29 bits (ID[28:0]) for the extended format. ID28 is the most significant bit (MSB)
and is transmitted first on the CAN bus during the arbitration procedure. The priority of an identifier is
defined to be highest for the smallest binary number.
Substitute Remote Request
This fixed recessive bit is used only in extended format. It must be set to 1 by the user for transmission
buffers and is stored as received on the CAN bus for receive buffers.
ID Extended
This flag indicates whether the extended or standard identifier format is applied in this buffer. In the case
of a receive buffer, the flag is set as received and indicates to the CPU how to process the buffer identifier
registers. In the case of a transmit buffer, the flag indicates to the MSCAN what type of identifier to send.
