5.6.3.3 Modes of Operation
The CAN Core unit assumes one of the seven
states described below:
–
STANDBY
. Stand-by mode is entered either on
a chip reset or on resetting the RUN bit in the
Control/Status Register (CSR). Any on-going
transmission or reception operation is not inter-
rupted and completes normally before the Bit
Time Logic and the clock prescaler are turned off
for minimum power consumption. This state is
signalled by the RUN bit being read-back as 0.
Once in stand-by, the only event monitored is the
reception of a dominant bit which causes a wake-
up interrupt if the SCIE bit of the Interrupt Control
Register (ICR) is set.
The STANDBY mode is left by setting the RUN
bit. If the WKPS bit is set in the CSR register,
then the controller passes through WAKE-UP
otherwise it enters RESYNC directly.
It is important to note that the wake-up mecha-
nism is software-driven and therefore carries a
significant time overhead. All messages received
after the wake-up bit and before the controller is
set to run and has completed synchronization
are ignored.
–
WAKE-UP
. The CAN bus line is forced to domi-
nant for one bit time signalling the wake-up con-
dition to all other bus members.
