Sense. If these synchronous wake-up events are configured then the power consumption of the PMU increases
in Sleep Mode. The increased current consumption is caused by an oscillator which generates the needed time
base (typ. 100 kHz).

Sleep Mode LIN Wake-up Timing
The wake-up procedure from Sleep Mode via MONx pins (instead of LIN) follows the same sequence as shown
in the figure above.
Stop Mode
The objective of the Stop Mode is to provide a data retention feature for the embedded MCU and the special
function registers (XSFRs). In the Stop Mode the core supply voltage VDDC goes from 1.5 V to reduced voltage
with the objective to reduce leakage current as much as possible. During the Stop Mode the dynamic behavior
