• 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 31:21 – IDMSK10:0: Identifier Mask
• Bit 20:3 – Reserved Bits
These bits are reserved for future use. For compatibility with future devices, they must be written
to zero when CANIDMn are written.
• Bit 2 – RTRMSK: Remote Transmission Request Mask
• 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.
