This fixed recessive bit is used only in extended format. It must be set to 1 by the user for transmission
buffers and will be stored as received on the CAN bus for receive buffers.
This flag indicates whether the extended or standard identifier format is applied in this buffer. In case
of a receive buffer, the flag is set as received and indicates to the CPU how to process the buffer
identifier registers. In case of a transmit buffer the flag indicates to the msCAN12 what type of identifier
to send.
