FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
up sources can be selected (maskable), which is not possible
in Sleep mode.
Figure 12 show the procedure to enter the Stop mode and
how the system is waking up.
Figure 12. STOP Mode Wake-up Procedure
Sleep Mode
In Sleep mode, the voltage regulator is turned off and the
MCU is not supplied (VDD = 0 V), also the RST_A pin is pulled
low.
To enter the Sleep mode, the Sleep bit in the System
Control Register has to be set.
Wake-up from this mode is possible by LIN bus activity or
the wake-up input L0, and is not maskable. The wake-up
behaves like a power on reset. The wake-up / reset source
can be evaluated by the L0WF and/or LINWF bits in the
Reset Status Register.
Sleep mode has a lower current consumption than Stop
mode, but requires a longer time to wake-up. The wake-up
sources can not be selected (not maskable).
Figure 13 show the procedure to enter the Sleep mode
and how a wake-up is performed.
