Freescale Semiconductor
During stop mode operation the path from the VSUP pin through the resistor chain to ground is
opened and the low voltage sense features are disabled.
The content of the configuration register is unchanged.

External Signal Description
This section lists the name and description of all external ports.
22.2.1
VSENSE — Supply (Battery) Voltage Sense Pin
This pin can be connected to the supply (Battery) line for voltage measurements. The voltage present at
this input is scaled down by an internal voltage divider, and can be routed to the internal ADC or to a
VSENSE
