MSCAN Controller (MSCAN08)
IDE — ID Extended
RTR — Remote Transmission Request
23.12.3 Data Length Register (DLR)
This register keeps the data length field of the CAN frame.
DLC3–DLC0 — Data Length Code Bits
284
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.
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.
The data length code contains the number of bytes (data byte count) of the respective message. At
transmission of a remote frame, the data length code is transmitted as programmed while the number
of transmitted bytes is always 0. The data byte count ranges from 0 to 8 for a data frame.
shows the effect of setting the DLC bits.
1 = Extended format, 29 bits
0 = Standard format, 11 bits
1 = Remote frame
0 = Data frame
