• Manufacturer Part Number: atmega32c1
• Description: Atmega32m1 Automotive 8-bit Avr Microcontroller With 32k/64k Bytes In-system Programmable Flash
• Manufacturer: ATMEL Corporation

16.10.5
7647A–AVR–02/08
CAN Enable MOb Registers - CANEN2 and CANEN1
• Bit 3 – ENERR: Enable MOb Errors Interrupt
• Bit 2 – ENBX: Enable Frame Buffer Interrupt
• Bit 1 – ENERG: Enable General Errors Interrupt
• Bit 0 – ENOVRT: Enable CAN Timer Overrun Interrupt
• Bits 5:0 - ENMOB5:0: Enable MOb
This bit provides the availability of the MOb.
It is set to one when the MOb is enabled (i.e. CONMOB1:0 of CANCDMOB register).
Once TXOK or RXOK is set to one (TXOK for automatic reply), the corresponding ENMOB is
reset. ENMOB is also set to zero configuring the MOb in disabled mode, applying abortion or
standby mode.
• Bit 15:6 – Reserved Bits
These bits are reserved for future use.
