The values read from this bit is indeterminate. Do not set this bit.
Enable Message Object
These bits provide the availability of the MOb.
It is set to one when the MOb is enabled.
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.
This bit is resetable by re-writing the CANCONCH of the corresponding
message object.
