Operating Modes

Figure 16-9. Overload Frame
The MOb is a CAN frame descriptor. It contains all information to handle a CAN frame. This
means that a MOb has been outlined to allow to describe a CAN message like an object. The
set of MObs is the front end part of the “mailbox” where the messages to send and/or to
receive are pre-defined as well as possible to decrease the work load of the software.
The MObs are independent but priority is given to the lower one in case of multi matching. The
operating modes are:
This device has 6 MObs, they are numbered from 0 up to 5 (i=5).
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 16-1.
In this mode, the MOb is “free”.
