V2.0 part B
• 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.
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.
• 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 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 – RB1TAG: Reserved Bit 1 Tag
RB1 bit of the remote or data frame to send.
This tag is updated with the corresponding value of the remote or data frame received.
