CANEN2 and CANEN1 – CAN Enable MOb Registers
• Bit 4 – ENTX: Enable Transmit Interrupt
• 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 - ENMOB[5:0]: Enable MOb
This bit provides the availability of the MOb.
It is set to one when the MOb is enabled (that is, 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 – Res: Reserved
These bits are reserved and will always read as zero.
