CAN Enable MOb Registers -
CANEN2 and CANEN1
CAN Enable Interrupt MOb Registers -
CANIE2 and CANIE1
• Bit 2 – ENBX: Enable Frame Buffer Interrupt
• Bit 1 – ENERG: Enable General Errors Interrupt
• Bit 0 – ENOVRT: Enable CAN Timer Overrun Interrupt
• Bits 14:0 - ENMOB14:0: 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 – Reserved Bit
This bit is reserved for future use.
