Self wake enable. This bit allows the TouCAN to wake up when bus activity is detected after
the STOP bit is set. If this bit is set when the TouCAN enters low-power stop mode, the Tou-
CAN will monitor the bus for a recessive to dominant transition. If a recessive to dominant
transition is detected, the TouCAN immediately clears the STOP bit and restarts its clocks.
If a write to CANMCR with SELFWAKE set occurs at the same time a recessive-to-dominant
edge appears on the CAN bus, the bit will not be set, and the module clocks will not stop.
The user should verify that this bit has been set by reading CANMCR. Refer to
Power Stop Mode
0 = Self wake disabled
1 = Self wake enabled
Auto power save. The APS bit allows the TouCAN to automatically shut off its clocks to save
power when it has no process to execute, and to automatically restart these clocks when it
has a task to execute without any CPU intervention.
0 = Auto power save mode disabled; clocks run normally
1 = Auto power save mode enabled; clocks stop and restart as needed
Stop acknowledge. When the TouCAN is placed in low-power stop mode and shuts down its
clocks, it sets the STOPACK bit. This bit should be polled to determine if the TouCAN has
entered low-power stop mode. When the TouCAN exits low-power stop mode, the
STOPACK bit is cleared once the TouCAN’s clocks are running.
0 = The TouCAN is not in low-power stop mode and its clocks are running
1 = The TouCAN has entered low-power stop mode and its clocks are stopped
