(20) CAN0 message data length register m (C0MDLCm)
Note
Cautions 1. Be sure to set bits 7 to 4 to 0000B.
The C0MDLCm register is used to set the number of bytes of the data field of a message buffer.
After reset: 0000xxxxB

The data and DLC value actually transmitted to CAN bus are as follows.
Type of transmit frame
2. Receive data is stored in as many C0MDATAxm register as the number of bytes (however,

the upper limit is 8) corresponding to DLC of receive frame. The C0MDATAxm register in
which no data is stored is undefined.

Setting prohibited
(If these bits are set during transmission, 8-byte data is transmitted
regardless of the set DLC value when a data frame is transmitted.
However, the DLC actually transmitted to the CAN bus is the DLC
value set to this register.)
