20.10.5 CANEN2 and CANEN1 – CAN Enable MOb Registers

• 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 (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.

– 0 - message object disabled: MOb available for a new transmission or reception.

– 1 - message object enabled: MOb in use.

• Bit 15:6 – Res: Reserved

These bits are reserved and will always read as zero.
