ATmega16M1/32M1/64M1
CANIDT1, CANIDT2, CANIDT3, and CANIDT4 – CAN Identifier Tag Registers
These bits are not cleared once the communication is performed. The user must re-write the
configuration to enable a new communication.
• Bit 5 – RPLV: Reply Valid
Used in the automatic reply mode after receiving a remote frame.
• Bit 4 – IDE: Identifier Extension
IDE bit of the remote or data frame to send.
This bit is updated with the corresponding value of the remote or data frame received.
• Bit 3:0 – DLC[3:0]: Data Length Code
Number of Bytes in the data field of the message.
DLC field of the remote or data frame to send. The range of DLC is from 0 up to 8. If DLC field >8
then effective DLC=8.
This field is updated with the corresponding value of the remote or data frame received. If the
expected DLC differs from the incoming DLC, a DLC warning appears in the CANSTMOB
register.
• This operation is necessary to be able to reset the BXOK flag
• This operation also set the corresponding bit in the CANEN registers
