DLC Register x (x = 0 to 15) (DLCRx)
DLC Register x (x = 0 to 15) (DLCRx) is the DLC register for message buffer x.

DLC Register x (x = 0 to 15) (DLCRx)
Figure 23.6-25 Configuration of the DLC Registers (DLCRx)
[bit15 to bit8] DLC3 to DLC0: DLC register x (x=0 to 15) (DLCRx)
●
Transmission
•
Set the data length (byte count) of a transmitted message when a data frame is transmitted (TRTRx of
the transmitting RTR register (TRTRR) is "0").
•
Set the data length (byte count) of a requested message when a remote frame is transmitted (TRTRx =
1).
Note:
Setting other than 0000
B
to 1000
B
(0 to 8 bytes) is prohibited.
●
Reception
•
Store the data length (byte count) of a received message when a data frame is received (RRTRx of the
remote frame request receiving register (RRTRR) is "0").
•
Store the data length (byte count) of a requested message when a remote frame is received (RRTRx =
1).
Note:
A write operation to this register should be performed in words. A write operation in bytes causes
undefined data to be written to the upper byte at writing to the lower byte. Writing to the upper byte is
ignored.
