Operating Modes

Tx Data & Remote Frame
Rx Data & Remote Frame
There is no default mode after RESET.
Every MOb has its own fields to control the operating mode. Before enabling the CAN periph-
eral, each MOb must be configured (ex: disabled mode - CONMOB=00).
Table 19-1.
In this mode, the MOb is “free”.
1. Several fields must be initialized before sending:
2. The MOb is ready to send a data or a remote frame when the MOb configuration is set
3. Then, the CAN channel scans all the MObs in Tx configuration, finds the MOb having
4. When the transmission is completed the TXOK flag is set (interrupt).
5. All the parameters and data are available in the MOb until a new initialization.
1. Several fields must be initialized before receiving:
