CAN Identifier Tag Registers -
CANIDT1, CANIDT2, CANIDT3,
and CANIDT4
4250C–CAN–03/04
V2.0 part A • Bit 31:21 – IDT10:0: Identifier Tag
V2.0 part B • Bit 31:3 – IDT28:0: 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.
• 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.
When a remote or data frame is received, this bit does not operate in the comparison
but it is updated with un-predicted values.
• Bit 0 – RB0TAG: Reserved Bit 0 Tag
RB0 bit of the remote or data frame to send.
This tag is updated with the corresponding value of the remote or data frame received.
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.
