2. Identifier 0 (X1hex)

This register sets the data length code and a part of the identifier.

Set this register for each message.

The bit configuration is as follows:

Address MSB

LSB

¥ 1h

76543210

(1) Format setting: IDFM

The microcontroller sets the message format.

At reset, the IDFM bit is undefined.

Operation

Standard format (ID = 11 bits)

Extended format (ID = 29 bits)

(2) Data length code: DLC3 to DLC0

This is control field data to set the number of bytes of a data field. 0 to 8 can be set.

At reset, these bits are undefined.

(3) Identifier: IDB28 to IDB26

These bits set the identifier field.

For standard format (IDFM = 0), the higher 3 bits of the 11 bits are set.

For extended format (IDFM = 1), the higher 3 bits (ID28 to ID26) of the 29 bits (ID28 to

ID0) are set.

At reset, these bits are undefined.
