Low-power stop mode enable. The STOP bit may only be set by the CPU. It may be cleared
either by the CPU or by the TouCAN, if the SELFWAKE bit is set.
Before asserting the STOP Mode, the CPU should disable all interrupts in the TOUCAN,
otherwise it may be interrupted while in STOP mode upon a non wake-up condition.
WAKE-INT can still be enabled by setting WAKEMSK.
0 Enable TouCAN clocks
1 Disable TouCAN clocks
FREEZE assertion response. When FRZ = 1, the TouCAN can enter debug mode when the
IMB3 FREEZE line is asserted or the HALT bit is set. Clearing this bit field causes the
TouCAN to exit debug mode. Refer to
0 TouCAN ignores the IMB3 FREEZE signal and the HALT bit in the module configuration
1 TouCAN module enabled to enter debug mode.
Reserved
Halt TouCAN S-Clock. Setting the HALT bit has the same effect as assertion of the IMB3
FREEZE signal on the TouCAN without requiring that FREEZE be asserted. This bit is set to
one after reset. It should be cleared after initializing the message buffers and control
registers. TouCAN message buffer receive and transmit functions are inactive until this bit is
cleared.
When HALT is set, write access to certain registers and bits that are normally read-only is
allowed.
0 The TouCAN operates normally
1 TouCAN enters debug mode if FRZ = 1
TouCAN not ready. This bit indicates that the TouCAN is either in low-power stop mode or
debug mode. This bit is read-only and is set only when the TouCAN enters low-power stop
mode or debug mode. It is cleared once the TouCAN exits either mode, either by
synchronization to the CAN bus or by the self wake mechanism.
0 TouCAN has exited low-power stop mode or debug mode.
1 TouCAN is in low-power stop mode or debug mode.
Wakeup interrupt mask. The WAKEMSK bit enables wake-up interrupt requests.
0 Wake up interrupt is disabled
1 Wake up interrupt is enabled
