(3) Setting a CAN Module into initialisation state
The following routine is required if a CAN module has to be set from normal operation into initiali-
sation mode.
Please notice that all CAN modules are automatically set to initialisation mode after reset. There-
fore the sequence is only required if the CAN module is already in normal operation.

Note: In case of permanent bus activity the program loops for a long time. Therefore, a time-out mech-
anism should be provided in order to limit the runtime of the routine.
Remark: x = 1 to 4 for the derivatives µPD703129(A) and µPD703129(A1), x = 1 to 2 for the deriva-
tive µPD703128(A)).
