Atmel ATmega16/32/64/M1/C1
CAN Enable Interrupt MOb Registers - CANIE2 and CANIE1
CAN Status Interrupt MOb Registers - CANSIT2 and CANSIT1
CAN Bit Timing Register 1 - CANBT1
• Bits 5:0 - IEMOB5:0: Interrupt Enable by MOb
Note:
• Bit 15:6 – Reserved Bits
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 - SIT5:0: Status of Interrupt by MOb
Note:
• Bit 15:6 – Reserved Bits
These bits are reserved for future use.
• Bit 7– Reserved Bit
This bit is reserved for future use. For compatibility with future devices, it must be written to
zero when CANBT1 is written.
