ATmega16M1/32M1/64M1
CANIDM1, CANIDM2, CANIDM3, and CANIDM4 – CAN Identifier Mask Registers
V2.0 part A
V2.0 part B
• Bit 31:21 – IDMSK[10:0]: 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 – Res: Reserved
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 – IDMSK[28:0]: Identifier Mask
