Figure 21-12. Standard Identifier Mapping
IDE — ID Extended
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
being received and indicates to the CPU how to process the buffer
identifier registers. In case of a transmit buffer, the flag indicates to the
MSCAN08 what type of identifier to send.
1 = Extended format, 29 bits
0 = Standard format, 11 bits
RTR — Remote Transmission Request
This flag reflects the status of the remote transmission request bit in
the CAN frame. In case of a receive buffer, it indicates the status of
the received frame and supports the transmission of an answering
frame in software. In case of a transmit buffer, this flag defines the
setting of the RTR bit to be sent.
1 = Remote frame
0 = Data frame
