10.10.7 Register Access Protection
Erroneous access to certain configuration regis-
ters can cause the hardware to temporarily disturb
the whole CAN network. Therefore the following
registers can be modified by software only while
the hardware is in initialization mode:
CBTR0, CBTR1, CFCR0, CFCR1, CFMR and
CDGR registers.
Although the transmission of incorrect data will not
cause problems at the CAN network level, it can
severely disturb the application. A transmit mail-
box can be only modified by software while it is in
empty state, refer to
States
The filters must be deactivated before their value
can be modified by software. The modification of
the filter configuration (scale or mode) can be
done by software only in initialization mode.
