CAN Identifier Tag Registers -
CANIDT1, CANIDT2, CANIDT3, and CANIDT4
V2.0 part A
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.
• Bit 31:21 – IDT10:0: Identifier Tag
Identifier field of the remote or data frame to send.
This field is updated with the corresponding value of the remote or data frame received.
• Bit 20:3 – Reserved Bits
These bits are reserved for future use. For compatibility with future devices, they must be written
to zero when CANIDTn are written.
When a remote or data frame is received, these bits do not operate in the comparison but they
are updated with un-predicted values.
• Bit 2 – RTRTAG: Remote Transmission Request Tag
RTR bit of the remote or data frame to send.
This tag is updated with the corresponding value of the remote or data frame received. In case
of Automatic Reply mode, this bit is automatically reset before sending the response.
• Bit 1 – Reserved Bit
This bit is reserved for future use. For compatibility with future devices, it must be written to zero
when CANIDTn are written.
