ATmega16M1/32M1/64M1
CANIE2 and CANIE1 – CAN Enable Interrupt MOb Registers
CANSIT2 and CANSIT1 – CAN Status Interrupt MOb Registers
CANBT1 – CAN Bit Timing Register 1
• Bits 5:0 - IEMOB[5:0]: Interrupt Enable by MOb
Note:
• Bit 15:6 –Res: Reserved
These bits are reserved for future use. For compatibility with future devices, it must be written to
zero when CANIE1 & CANIE2 are written.
• Bits 5:0 - SIT[5:0]: Status of Interrupt by MOb
Note:
• Bit 15:6 – Res: Reserved
These bits are reserved and will always read as zero.
• Bit 7– Res: Reserved
This bit is reserved for future use. For compatibility with future devices, it must be written to zero
when CANBT1 is written.
