CAN Time Stamp Registers - CANSTML and CANSTMH
V2.0 part A
V2.0 part B
• 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.
• Bit 0 – IDEMSK: Identifier Extension Mask
• Bit 31:3 – IDMSK28:0: Identifier Mask
• Bit 2 – RTRMSK: Remote Transmission Request Mask
• Bit 1 – Reserved Bit
Writing zero in this bit is recommended.
• Bit 0 – IDEMSK: Identifier Extension Mask
• Bits 15:0 - TIMSTM15:0: Time Stamp Count
CAN time stamp counter range 0 to 65,535.
